Description Martin Nowak 2011-11-23 04:48:56 UTC 
struct Foo
{
    static size_t index(size_t v)()
    {
        return v;
    }
}

enum s = Foo.index!(0)();

----
CTFE internal error: cannot evaluate (Foo , index)() at compile time
----

In CallExp::semantic around line 7513:

        if (!f->needThis())
        {
            VarExp *ve = new VarExp(loc, f);
            e1 = new CommaExp(loc, ue->e1, ve);
            e1->type = f->type;
        }

a comma expression is created with ue->e1 being a TypeExp.
The CTFE interpretation can't handle this case in CallExp::interpret.
