we've moved (or at least, im trying to move) everyone to the idea that in order to get at a mapper, you say class_mapper(someclass), which compiles. but that doesn't account for non-primary mappers anyway.

i wonder, if something goofy like a compile() step within __getattr__() might be a way to generically handle this, without forcing all attributes to do "if not compiled:compile()" ?
