[Swift-devel] foreach iteration parameter type

[Ben Clifford]

the foreach syntax admits a type declaration for the iteration parameter.

the iteration parameter must necessarily always be of the type of the 
members of the supplied array to iterate over.

the iteration parameter type has never been checked in actual 
implementation.

I'd like to replace the broken code path with a compile error indicating 
that specifying a type is no longer supported; and in a while remove that 
entirely from the syntax.
