7406 – tuple foreach doesn't work with mixed tuples

template TypeTuple(T...)
{
 alias T TypeTuple;
}
template foobar(T)
{
 enum foobar = 2;
}
void main()
{
 foreach(sym; TypeTuple!(int, double)) // OK
 pragma(msg, sym.stringof);
 foreach(sym; TypeTuple!(foobar)) // OK
 pragma(msg, sym.stringof);
 foreach(sym; TypeTuple!(main)) // OK
 pragma(msg, sym.stringof);
 foreach(sym; TypeTuple!(int, foobar)) // Error: type int has no value
 pragma(msg, sym.stringof);
 foreach(sym; TypeTuple!(int, main)) // Error: type int has no value
 pragma(msg, sym.stringof);
}
----
As soon as a symbol is part of the tuple it is treated as expression
tuple. Foreach with an expression tuple then tries to use each tuple
element as initializer which fails for types.
