patch against dmd commit 8e2b13b025626127e5e2a0fb90326e655f3deac8 

here is the discussion:
http://forum.dlang.org/thread/vesvrfaipppwtenleqjr@forum.dlang.org

summary: compiler should accept both foreach (v; smth) and foreach(auto v;
smth) forms. this can be noncense from compiler writer PoV, but ordinary
language user will not be confused by declaring variable without any type.

this change will not break any existing code ('auto' is purely optional).

patch attached (parser fix and two simple test cases).
