Note that this is already supported (apologies if I've got the syntax
slightly wrong):
foreach (i, ref tile; map) { ... }
That's a local variable too. It could have instead been defined such that
"tile" is an alias for "map[i]", but that would be a little strange.
That's a very good point.
Technically, foreach is implemented such that its body is a function and the
"i, ref tile" is the parameter list. But I think that's beside the point.
Given that enabling foreach's syntax for general D functions, i.e.
myLoop(i, ref tile; map) { ... }
has been discussed several times in this newsgroup, the fact that "i, ref tile"
is the parameter list of a delegate is not beside the point.
