Comment (by SimonKing):
With #15801, I get
{{{
sage: L = [Coalgebras(QQ), Sets().Finite(), Algebras(ZZ),
SimplicialComplexes()]
sage: %timeit Category._sort_uniq(L)
10000 loops, best of 3: 25.2 µs per loop
sage: %timeit Category._sort(L)
100000 loops, best of 3: 6.22 µs per loop
}}}
With the current branch from here, I get
{{{
sage: L = [Coalgebras(QQ), Sets().Finite(), Algebras(ZZ),
SimplicialComplexes()]
sage: %timeit Category._sort_uniq(L)
100000 loops, best of 3: 14.1 µs per loop
sage: %timeit Category._sort(L)
100000 loops, best of 3: 5.61 µs per loop
}}}
Making `sage.categories.category` Cython means that we could now cimport
`WeakValueDictionary` and get a bit more speed by accessing the contents
by cdef methods.
