Sure this answer by Sage is less cryptic:
sage: p=Permutation([4,1,2,5,3])
sage: type(p)
<class
'sage.combinat.permutation.StandardPermutations_all_with_category.element_class'>
but it prevents me (and perhaps others) to do any development in such a
system :-(
I think the thread about a pseudo "Code of Conduct" is indeed intended to
prevent guys (yes, guys) like Nathann to say simply that in some areas Sage
code is a whole mess. Too bad.
