[sage-devel] Ping for review: Element.__hash__ rework

2015-10-16 Thread Nils Bruin
As far as doctests go, we have now figured out how to successfully remove the problematic "hash(str(a))" implementation on sage Element. The ticket just needs some trivial doctest additions to make a beancounting patchbot plugin happy. The changes on the ticket are pretty straightforward, but th

Hello everybody, I have two remarks to make about the patchbot, and I have no idea if I am just misinterpreting/misreading or if there is something wrong: 1) The ticket at #19353 fails to build the doc. I built it manually and noticed a missing reference ([Kohnert07]), though this missed refer
