D complains that t does not have a this.
I'd just like to print the literal text that was passed to T.
(which I actually do in ctfe) This is so I can have some sort
of debug output of what was passed to t.
that error is probably related to what you're passing as t,
which leads to the obvious question: what sort of things are
you passing as t?
Yeah, I forgot to add a private local variable and it was
complaining... I didn't realize this because it was working
before I started refactoring stuff.
I guess it would be nice to assert a proper error if t doesn't
exist rather than the error it gave. (I'm suppose to be passing
it a field of a class so it should exist)
Is there any way to test for "existance" of an alias?
