A very minor change that would be elegant and easy for

Allowing just a single number to mean the end point and a

starting point of zero is assumed, just as with iota it's
possible to write it iota(5) or even 5.iota, it assumes unless
otherwise specified that you mean 0 to be the starting point.
Would this be a reasonable enhancement request for me to make
or
does it collide with something?
I would argue that the mistake is that iota(5) works. That's
not at all clear,
and
foreach(i; 5)
//stuff
is no better. Regardless, all such an enhancement would do is
save you a
little bit of typing. It adds no actual functionality to the
language, so I
_really_ don't think that it makes sense to implement anything
like that.

Regardless of this particular suggestion's value, I think you're
wrong to dismiss readable terseness and saving typing as
mattering, it's one of D's advantages over C++ that it makes a
lot of things far easier to do and understand because they're not
a horrid mess.
