I don't think it should be using __traits(compiles) either. I'd
prefer to see built from the other reflection primitives...
though I'll grant that compiles is flexible.
hasMember!(Range, "empty")
isn't as specific as the current test... and
is(typeof(Range.init.empty) : bool)
isn't as flexible (I don't think that takes an empty that returns
an opCast:bool item)
But regardless, I still kinda prefer the idea of building these
reflection helper functions so they do cover the cases nicely...
then a helper function that takes a list of conditions and tells
you which one failed... hmm, this is getting interesting.
