Comment:
I understand that you want to correct the function `is_endormorphism`, but
there is something strange about combinatorial class comparison.
For instance, I get the following:
{{{
sage: Words('ab') == WordPaths('ab')
False
sage: Words('ab') <= WordPaths('ab')
True
sage: Words('ab') >= WordPaths('ab')
False
}}}
Wouldn't we want
{{{
sage: Words('ab') == WordPaths('ab')
True
}}}
or is there something I miss ?
If it is a problem, maybe it's not necessary to fix the `__eq__` operator
now but do it in another ticket, but since you're at it...
