Comment:
Hello,
1. Could you motivate a bit more this change. I do not find simpler to use
a `key` function instead of a `cmp` function.
2. It does not apply on the most recent version of Sage.
3. I found the docstring confusing
{{{
def indices_key(self):
r""""
A comparison function on sets which gives a linear extension
of the inclusion order
}}}
This is '''not''' a comparison function (which would have pairs as
input)!
More to come, when you answer 1
Vincent
