Comment(by ncohen):
Hello !!!!
I remember having tried the two This patch has had many different versions
At some point some of these classes were "cdef class", then got back to
usual python... I remember having noticed at some point that if I were to
define < > == ... using richcmp instead of the usual python operators,
other low-level comparators would be used by default instead of mine.
Well, I had many troubles with this class, so perhaps I should give it a
try again now that it works again :-)
It is not normal at all that nothing works with CBC :-/
Could you tell me which kind of errors you get ?
Thank youuuuuuuuu !!
