I think I ended up working around this by putting the essential information
into the classes themselves, and then having one Traits template that covered
built-in types.  Another big template did bunches of static structural tests to
tease the needed information out of a class.  

In my case that was sufficient.  But it's certainly more cumbersome to deal
with.   Perhaps you can explain your case in a little more detail and we might
be able to come up with some workaround?
