I often find myself wanting to write this:

In the case that I just want to do something n times and I don't
actually care about the loop counter, but this doesn't compile.
You can do this:
for(;;) {}
If 'for' lets you omit any of the loop terms, surely it makes
sense
that foreach would allow you to omit the first term as well?
I see no need to declare a superfluous loop counter when it is
unused.
Seems like a nice idea. Especially useful when it comes to
reading other people's code:
foreach (i; 0..n)
{
some();
long();
list();
of();
tasks();
}
// I always double back--"wait, where did they use `i`?"
