actually, `foreach (v; rng)` looks like `foreach` is *reusing*
*existing* *variable*. most of the time you can put
`immutable` or something like that there to note that it is
not reusing (purely cosmetical thing), but sometimes you
cannot, and then `auto` is perfect candidate... but it is not
allowed. (sigh)
Chipping in my agreement. foreach(x; y) makes as much syntactic
sense as for(x = 0; x < y; x++) where x was not previously
defined. One does not expect something that does not look like
every other variable definition in the language to be defining
a new variable.
Furthermore, if foreach(int x; y) is legal then why isn't
foreach(auto x; y)?
