Thank you very much! Could you also explain why <wink>? (e.g. why can I
make items() a classmethod but not __iter__, and how does
__metaclass__.__iter__ get called from iter(ClassIter)? -- it doesn't
show up when using dir()...)

Just doing my first meta class project since Smalltalk in the early
90's...
