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.

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.
