I don't think I've ever come across a case where I want to assign
increasing-by-one values to adjacent variables. Have you?

ok, I admit the rule difference between variable and constant declaration 
does matter:

var (
a int = iota
b// should autocomplete

No, it is not an unrelated rule. Because it means that "just like for
consts" isn't an argument. You need, at the very least, answer the valid
question ("what happens with that var-declaration and why?") raised about
your proposal. Or better yet, realize that var and const declarations
behave very differently and thus "consistency" isn't an argument to add
something otherwise useless.

 For constants it's expected to reuse the last iota expression when
 absent. Do you propose that

 var (
 a = iota
 b
 )

 will become valid and initialize a to 0 and b to 1?

 If so, is it valid and what shall happen when one writes

 var (
 a = iota
 b
 s string
 d
 )

 ?

For the same rule, I mean just copying the corresponding part from last

Yes, declared constant must be assigned. This is an unrelated rule for this 
topic.

Re: [go-nuts] why iota can't be assigned to variables?

['Axel Wagner' via golang-nuts]

but
const (
a = iota
b
s string
d
)
is not a valid declaration. You can't say "the rule is the same for
constants".

Again: const-declarations and variable declarations are very different. You
can not argue "it's the same"; it's not.

Do you propose that

var (
a = iota
b
)

will become valid and initialize a to 0 and b to 1?

If so, is it valid and what shall happen when one writes

var (
a = iota
b

d
)

?

If it's not valid, why?

How can that be claimed when still nobody ever seen any specification of
what var foo = iota shall do at all? The space of possible semantics is
unbounded. The sane subspace seems to me to be of zero volume, but will you
please just explain what you expect from assigning iota to a variable?

Re: [go-nuts] why "iota"?

…I was not correcting you. I was saying that the whole world appreciates the 
strength of Russian math education as consistently demonstrated in the 
International Mathematical Olympiad. (This is the Olympics that excites me, the 
place for people who can wrestle with exponential generating functions as ably 
as people in the other Olympics can throw a stick or kick a ball.)

The problem is that we have somewhat incompatible denominations for
these education-related terms, and what americans call "high school" is
called with what translates like "middle school" here.

Re: [go-nuts] why "iota"?

If you're looking for Greek pronunciation of Greek letters, there's this:

which agrees with what I learned in high school (and what is now stuck in 
my head).

  Make Iota great again!

Re: [go-nuts] why "iota"?

[Rob Pike]

It is my understanding that the use of iota in the phrase "not one iota of
difference" relates to the epistemological debate about the difference of
the (Greek) terms homoousian and homoiousian.

But yes, Ken suggested iota for the counter and, since all three of us
(Ken, Robert, Rob) had implemented APL interpreters, it seemed a perfect
thing to us, however insignificant iotas may or may not be in gnosiology.

Re: [go-nuts] why "iota"?

[Michael Jones]

Iota is indeed a Greek letter, the one from which western alphabets inherited 
the letter ‘i’ (⍳). If you read Comparative Grammar of Greek and Latin 
(Darling, 1933) or the New Comparative Grammar of Greek and Latin (Sihler), 
you’ll discover that iota and its friend upsilon share quite a bit of history. 
They both come from Phoenician, and they both brought the magic now exhibited 
by the modern English ‘Y’ (Υ), of having both consonantal and nonconsonantal 
forms. 

 

This was one of the great mysteries from my childhood, where I was taught in 
school that the English vowels were A, E, I, O, U, and sometimes, Y. That 
baffled me, how Y could be a “sometimes” vowel, as if that made it “less than a 
real vowel.” That seemed crazy to me. Certainly Superman was not less of a 
superman because he was sometimes Clark Kent. In fact, I tried to recruit 
people to my Vowel Movement to get Y classified as a vowel that was sometimes a 
consonant, more in keeping with its gravitas from the special vowel role. 
Amazingly nobody in my school cared and no teacher could explain the dual 
status of ‘Y’.

 

You can imagine my delight to learn that I and Y came to English from Phoenicia 
by way of Greece and in both languages they had this kind of dual 
citizenship—but in both they were regarded as vowels with specialness. So the 
vowel movement turns out to be historical fact and not just a little boys hope.

 

Iota’s role in APL as an index generator is also central as the basis of many 
vector functions—a typical Go loop on an index variable “for i:=0; I < N; 
i++{x[i] = F(y[i])}”is natural in J or APL as “F()” mapped across “iota N.” The 
index generator role, “⍳ 5” -> “1 2 3 4 5” is the inspiration for Go’s iota in 
blocks of constant declarations. It is very common in C and C++ CPP headers to 
see long chains of definitions like:

 

#define ConditionA 0

#define ConditionB 1

#define ConditionC 2

:

 

and the Go team (Ken Thompson IIRC) saw that “0 1 2…” and thought of iota. This 
was great!

 

Pronunciation is simply the natural way, if you’re Phoenician or Greek. If not, 
have a listen at the Oxford website, which has “real” and Americanized 
pronunciations:

 

https://painfulenglish.wordpress.com/2013/08/03/how-to-pronounce-greek-letters-in-english/

http://www.oxfordlearnersdictionaries.com/definition/english/iota

 

According to the OED, the meaning of iota as “a small or insignificant 
quantity” derived from iota being the smallest letter in the Greek alphabet 
(i.e., physical orthography.)

 

P.S. Yes, this is a little bit more detailed than was necessary…but…many of us 
are working hard to find joy today.

... 2. A jot; a very small, inconsiderable quantity. 

hope that helps to clarifies it

​Being a crude Texan, I pronounce it like "eye ough ta"​

​(which is also how I pronounce "i ought to" because, well, I'm a Texan!
[grin]). BTW, it's also the 9th letter in the Greek alphabet.​
​ref: https://www.youtube.com/watch?v=0T1sUNyqWPo which is not how I
pronounce it, but more like Marvin says.​

Speaking as a former APL language implementer, I think the Go use of
iota is very much in line with the APL definition:  it produces
successive integers.  APL, being an array oriented language, produces
them all at once, but the basic idea is the same.

In APL, ⍳7 produces the vector (one-dimensional array) 1 2 3 4 5 6 7.

Iota is pronounced eye-OH-tuh.
