Comment (by mmarco):
Hm, i am now forgeting about the __cmp__ method, and just implementing
comparison through _cmp_ ... but that makes comparison by equality not
working.
I get something like this:
{{{
sage: F=FreeGroup('a,b,c')
sage: F.inject_variables()
Defining a, b, c
sage: a._cmp_(a*b/b)
0
sage: cmp(a,a*b/b)
0
sage: a.__cmp__(a*b/b)
0
}}}
but
{{{
sage: a==a*b/b
False
}}}
That didn't happen in the previous version.
