Note to self: the numeric::numeric ctor transfers ownership of the mpz_t, so no clear in that one code path. Tests pass now! Setting this to needs review for now, a better valgrind integration needs the pypi/valgrind PR that will be tracked there. |

Documentation preview for this PR (built with commit 2286629; changes) is ready! 🎉 |
