--- Comment #2 from Richard Smith <richard-llvm at metafoo.co.uk> ---
I believe clang is following the language rules here. You can't mention a
reference from a constant expression unless we know the object the reference
binds to, because the evaluation semantics of an lvalue include determining the
object it denotes.

As far as I can tell, other compilers sometimes accept this because they do
some kind of early AST folding that loses the distinction between a direct
access to a static data member and a class member access.
