Description changed by startakovsky:
Old description:
> Given two maps f and g, why would it be the case that `f == g` returns
> `False`, when the maps are identical, and when comparing the
> `set(f.domain())` == `set (g.domain())` and the same for `codomain`, we
> get `True`?
>
> Is there a functional reason why comparing domains of functions we can't
> wrap them as sets before comparing them? Are FiniteEnumeratedSets
> supposed to function in such a way that they may not be considered equal
> unless converting them to a set first?
>
> Please advise.
New description:
Is there a functional reason why comparing domains of functions we can't
wrap them as sets before comparing them? A domain and codomain of a map
are sets and ultimately should be compared as such when order doesn't
matter.
Please advise.
