Oh, I see what you mean.
So the problem is that built in types don't have "members" per
se, they have "magic". The built in properties don't count to
`hasMember`. You could probably do `if(__traits(compiles,
mixin("a." ~ member))` though.

yeah, just built in properties/members don't pass the same
existence checks so that's confusing your template constraint.
