Hi Simon, The following is a problem for my work at #18758, which aims at making arithmetic operations faster that are defined via category element/parent classes: sage: Sym = SymmetricFunctions(FractionField(QQ['t'])) sage: ks3 = Sym.kschur(3) sage: ks5 = Sym.kschur(5)

Hi all, I've been working on a major revamp of symmetric functions. It is possible that the changes I have been making conflict with Martin's recent changes to the `principle specialization` and have broken the queue. They shouldn't technically interfere, but for some reason 'merge' wasn't
