> The changes look good, except the removal of the three checks for n < 0
in `pow_mpz_t_tmp` and `pow_ZZ_tmp` where a ValueError is raised. While I
understand that Cython will ignore those errors, I think the right option
is to open another ticket and modify what is done, rather than just
removing the checks. With these changes it's easier for these functions
to segfault on incorrect input.
Does this refer to how Cython used to work? Does it make sense to add an
`except NULL` to the function definition now? I stumbled upon this while
working on #13591.
