Comment:
Thanks Florent, and thanks for using this occasion to cleanup my code!
Can you fix the copyright dates? Mine should be 2009, and yours 2010
I like the idea of using Python's standard convention for private
attributes; on the other hand, I am a bit worried about emulating Python's
mechanism. In particular, we could eventually get in trouble with the
class name hacking we do for pickling:
{{{
sage: Sets.ParentMethods.__name__
'Sets.ParentMethods'
}}}
I haven't found a way to *use* Python mechanism. So instead, what about
using ``__classcall_private__``, and doing the test with
'__classcall_private__' in cls.__dict__?
(I also prefer ``private`` to ``no_inherit``).
Cheers,
