write it iota(5) or even 5.iota, it assumes unless otherwise

that you mean 0 to be the starting point. Would this be a

enhancement request for me to make or does it collide with
something?
I don't see what this would gain over:
foreach (i ; 0 .. 5)
Just like the terser iota, it's more elegant and easier for newer
users. The fewer symbols there are in code the easier it is to
parse for the user (up to a point). It's also more consistent
with iota. It also means that a foreach that iterates a function
return value can be written in the same manner whether it returns
an array or an integer, again more consistency.
