I thought __new__ was called upon construction of the _class_ object
that "Meta" is the type of. Then it would be available at the time of
the definition of my class. Or am I mistaken?

Is there no way to create a class variable that exists during
definition of the class? (I cannot imagine there isn't, since
technically it's possible and manually it can be done...)

"painless" metaclasses) cannot be used without new-style classes (or
rather, that they don't work where you cannot explicitly use new-style
classes). I haven't so far

n as far as I can remember. I do not get that. Why is the
"L[:]" idiom more memory-efficient here? How could the increased efficiency be
demonstrated?
