Going to concrete proposals, i would create a wiki page where people could
start writing small comparisons that they know in concrete cases.

Hello everybody !
I just met two situations in which we need to rename a module: 1) not

Do we currently have a "deprecated_module_alias" implemented in a way

As far as I can see (in sage.misc.superseded, no). Might be useful to

I have several bad answers to give you:

of your points are equal but they have a different hash. This confuses
dictionaries (and graphs).

Yes, I agree the hash should be different as the points are not exactly the
same interval. However, in trying to explore the interval comparison this
also may have exposed a bug in the equality check for projective points.
Since the CIF is returning False for == and != the __eq__ check for

DiGraphs consider that two points u,v with u==v are the same points.
If those (equal) points have different hash values, I have no idea of
