Hello,
I am trying to simplify and optimize the comparison part of the
coercion framework at #17890.
There is one convention we currently have in Sage which is posing an
obstacle: if a Python class (not a Cython cdef class) inheriting from
Element defines both _cmp_c_impl and __cmp__, then
For the last two in your list it is quite possible that I wrote the
code and did not understand what I was doing at the time, just happy
that what I wrote worked. (Particularly true of the
WeierstrassIsomorphism code which I wrote in 2007, the very first
Sage/python code I ever did write). So
The few times I played with comparison functions, I found what we have
quite confusing, especially the discrpancy between Python and Cython
classes, so any simplification would be welcomed.
And if it also eases the transition towards Python 3 that would be great.
