It was marked duplicate. I read the comments to the previous 
issue and felt like reading C++ discussions, except C++ is a lot 
better documented.

Anyway surely `__traits(getAttributes, Bar.t)` compiles. The 
compiler should "need 'this'" when it actually need 'this' - 
unless there are attributes that can be bound to 'this'.
