void main() { int[256] data; foreach (ubyte i; 0 .. data.length) {} // OK foreach (ubyte i, x; data) {} // Error } test.d(4,5): Error: index type 'ubyte' cannot cover index range 0..256

Similar to Issue 1878. I think I've even seen this bug reported somewhere though.. And a similar thread from 2011: http://forum.dlang.org/thread/[email protected]

So I think it's a bug (or missed case) in the recent improvements of foreach.
