Comment (by dimpase):
In the attached patch I've cleaned up
{{{combinat/integer_vector_weighted.py}}} which was making permutations
from anything that crawls, and also removed some, although not all,
{{{check_input=False}}} from {{{combinat/permutation.py}}}.
One has to decide what to do with Robinson-Schensted. As it can be applied
to non-permutations, it must leave the Permutation class and get a real
place somewhere. This would allow a good cleanup of
{{{combinat/permutation.py}}}.
