Isn't this the same argument for .dynamicType over type(of:) though?
Given that that debate has been settled in favor of the latter, I think the
question today is how best to come up with a consistent scheme.
Earlier in this conversation, it was pointed out (by Matt, I think?) that
one key advantage of type(of:) is that it takes on a syntax that is
actually possible to write in Swift, since one cannot extend Any.
If we take this principle to its logical conclusion, properties (of a type
or instance) which apply to Any should be global functions.
