Robert Bradshaw commented on BEAM-5621:
---------------------------------------
A proper fix would to not require sortability. (This has actually come up
before, we should accept a list of matchers and determine if any permutation of
the inputs satisfies them, which can be done in O(n^2) applications + O(n^3)
arithmetic time.
Note that this is not just an issue for Python long, but ints vs. floats, and
any other objects that may compare equal across types.
In the short term, perhaps a quick hack is to try sort + compare, and that
failing, fall back to the type-aware sort + compare, and also clearly indicate
that this is not promised to be backwards compatible.
> Several tests fail on Python 3 with TypeError: unorderable types: str() <
