Reposting this from my mailing list message so it doesn't get lost:

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.
