foreach problem

[Dejan Lekic]

Compiling foreach_bug.d produces an error, while compiling foreach_ok.d does
not. IMHO that is a bug - it is clearly stated in current specification of The
Language (http://www.digitalmars.com/d/statement.html#ForeachStatement) that
variable can be declared outside.

Kind regards

Dejan
