https://github.com/D-Programming-Language/dmd/commit/8baaaf675e7d50b1160f81b9a27aef106f584968 introduced a regression concerning __traits(compiles, ?):
---
struct Foo {
   int a;
}
static assert(!__traits(compiles, { return Foo.a; }));
---

The assert doesn't pass anymore with the aforementioned commit in place, i.e. __traits(compiles, ?) returns true. If the delegate was used in actual code, semantic analysis would later give a ?need this? error.

I'm not quite sure what the best/correct fix for this is.
