Comment (by SimonKing):
Nicolas, do you think that the new code layout (in particular for
`Category.join`) is sound?
Repeating the benchmarks:
{{{
sage: from sage.categories.category_with_axiom import canonicalize_axioms,
all_axioms
sage: L = ["Commutative", "Connected", "Commutative", "WithBasis",
"Finite"]
sage: %timeit canonicalize_axioms(all_axioms, L)
100000 loops, best of 3: 3.81 µs per loop
sage: L = [Coalgebras(QQ), Sets().Finite(), Algebras(ZZ),
SimplicialComplexes()]
sage: %timeit Category._sort(L)
100000 loops, best of 3: 6.01 µs per loop
sage: %timeit Category._sort_uniq(L)
100000 loops, best of 3: 15.9 µs per loop
sage: L = [Coalgebras(QQ), Sets().Finite(), Algebras(ZZ),
SimplicialComplexes()]
sage: %timeit Category.join(L)
1000 loops, best of 3: 510 µs per loop
}}}
