> One more thing for the doc: for trac tickets you should use
{{{:trac:`17730`}}}. That will create automatically a link in the compiled
documentation.
OK.
> More seriously, we definitely do '''not''' want to test irreducibility
at the beginning. You can possibly add this test in between step 2 and 3.
That would prevent some useless factorization. But if you do so, I want to
see some benchmarks first.
I do not understand your remark: irreducibility was tested as the first
step before, and moving this test later is precisely the purpose of my
ticket.
