[sage-combinat-devel] Do we want to have the category of associative magmas?

2013-04-29 Thread Simon King
Hi! Currently, I try to resume writing code for modules over finite dimensional path algebra quotients. At #12630, Jim Stark proposes some code that apparently has a non-empty intersection with what I need, but much of it is orthogonal. So, I'm seeking advice how to fit my experimental code with
