Minor enhancement request, but the language should allow using "foreach"
without specifying an iteration name. THis can be useful when you want to
iterate a fixed amount, without caring about the index. For example, when you
want to "popFrontN exactly" (popFrontN is safe, so slightly slower), you'd want
to write:

foreach( ; 0 .. n ) r.popFront();

Right now, if you do this, you get:
main.d(5): Error: basic type expected, not ;
main.d(5): Error: no identifier for declarator int

for can do without declarators, I don't see why foreach can't have the above
syntax.

Just a minor ER, but I think it would make foreach that little extra user
friendly.
