No one noticed yet that the a..b:c syntax causes ambiguity? Tell me,
how do you rewrite this using the new proposed syntax:
auto aa = [iota(a, b, c): 1, iota(d, e): 2];
Right, that's why in another post I have said that syntax replaces most iota
usages. There are some situations where you can't use it well. This is another
situation I've shown in the enhancement request:
iota(10.,20.)
Writing it like this is not sane:
10...20.
Interval is clear only as long as there's no step value mentioned.
Having a step value is quite a stretch from the usual notion of an
interval.
Right, but I think it's acceptable still, and better than iota.
I like a lot so's suggestion "walk". I'm not sure it's much clearer
than iota though.
It's better than iota, but not by much.

I think it's much better. Even having "steps" (or a stepsize) is obvious with
walk.
iota only makes sense when you know this from other languages/libraries or if
your native spoken language has a similar word that can be somehow connected.
http://en.wiktionary.org/wiki/iota doesn't give a real connection (and two
English->German dictionaries I've checked don't either - one only listed iota as
the greek letter, the other had mentions about something tiny) - it's just
something small like that greek i-without-a-dot letter.
There's nothing that connects it to a range of values with a fixed step size.
That page looks listing various meanings in foreign languages, but mostly
stincks with the greek letter; it does not mention any sense everday sense iota
actually has. Example fro fr.wiktionary:
# Nom de ι, Ι, neuvième lettre et quatrième voyelle de l’alphabet grec.
Équivalent du i latin.
# Petite quantité négligeable, presque rien.
Free translation: little negligible quantity, nearly nothing.
There are good chances iota has a similar meaning in numerous languages,
especially romance ones. Bearophile, Andrei?
