It's standard Python idiom (if a module has a main class give them the 
same name), but now that the bases for a class can be pretty much 
everything that is callable, in stead of only modules as it used to be, 
it can lead to strange errors.

But I think NibLoader should be able to detect this situation (not sure 
though, I don't have the code handy, and I still haven't read Just's 
message which will hopefully finally make me understand metaclasses).
