Ah, it seems you've actually found a bug in the algorithm. I mistyped

I would just use separatevars or factor on the expression to try to
split it apart, and then just match against x**n*y. I can't think of

I would recommend going for a TODO rather than a NotImplementedError

You can delete an upstream branch with git using
git push remote :branchname
(note the colon). The usual syntax is
git push remote sourcebranch:remotebranch
putting nothing for sourcebranch causes it replace remotebranch with
the empty branch (i.e., delete it).
It's also best to always
