Ah, "int" is the "lower" level, native integer and "Int" is the raku. An "int"
is immutable or something? The page
https://docs.raku.org/language/numerics#Native_numerics
has:
my int $x = 2⁶³-1;
say $x; # OUTPUT: «9223372036854775807»
say ++$x; # OUTPUT: «-9223372036854775808»
But I see
> my int $x = 2⁶³-1
9223372036854775807
> say $x
9223372036854775807
> say ++$x
Cannot find method 'qast' on object of type NQPMu
NQP (Not Quite Perl) Mu has no "qast" method - qast is the successor to past,
Parrot AST and AST is Abstract Syntax Tree. I guess $x *is * the int, not an
container/variable holding an int value.
Man, there's a lot I don't know about raku! That section on colon pairs
cleared up a lot.

Hi Andy,
A quick test with my (older) Raku install and I was able to get one of the
examples (Daniel's) below to work. However I had to use "Int" instead of "int":
user@mbook:~$ raku

HTH, Bill.

I was impressed I could copypasted that in the text/terminal sesion of raku's
REPL and have it work. As a matter of fact:
> sub foo($) { ++⚛$c }('a' | 'b,b' | 'c');
any(1, 2, 3)
> say $c;
3
but, trying it without the cabbage, er, atomic symbol

0

Cannot find method 'qast' on object of type NQPMu
but my raku's a tad long in tooth
$ raku -v
This is Rakudo version 2020.05.1 built on MoarVM version 2020.05

WATs are everywhere, and (I'm not trying to pick on one language
here), I find this SO question to be intruiging:
https://stackoverflow.com/q/58340585/7270649
Joseph (and Ralph): thanks for starting off this conversation!
Fernando and Vadim: amazed at your code!
Andy: good questions always welcome!
Daniel: Thank you for your confirmation on EVAL. Also, I tried parsing
the ATOM SYMBOL character to look at classification, and this is the
best I could do (in the Raku REPL):
> say "⚛".uniprop
So
> dd "⚛".comb>>.uniprop
("So",)
Nil
> say "{uniparse 'ATOM SYMBOL'}"
⚛
> say "{uniparse 'ATOM SYMBOL'}".uniprop
So
> say "{uniparse 'ATOM SYMBOL'}".uniprop('Alphabetic')
False
HTH, Bill.
PS. Cannot sent this email in 'plain text' mode as ATOM SYMBOL disappears.

No, it's not an abbreviation for anything – it's the word "what", but
pronounced in a way that
indicates the speaker is surprised/confused. More specifically, it's a
reference to the WAT talk (a
really good one, even if it is about a different language)

(All of that is pretty much strait from the glossary, by the way)
