Yes, this is the best design so far.

I'd also note that using foo without either "&" or "()" is still necessary to get access to foo's set of properties:

auto s = foo.stringof;
auto m = foo.mangleof;
// etc

Other than that I'm absolutely agree with both of you.
Too bad language designers don't participate in the discussion.
