[no reason to generate symbols for meta-class names because they aren't

[Use strings, avoid identity assumption]
Well, in this case, I suddenly noticed I shouldn't even have
meta-classes where they were appearing, so the issue is moot. 

At some point I thought this might be a performance hotspot. But on
further thought, if as you note I'm using the identity assumptions it
might be more proper to reference the classes themselves and use their
identity, and only generate names for display. 

Actually, that might still be a worthy change, even if I solved that
other bug.
