I just tracked down a nasty bug completely messing up my math experiments to the following internal caching mechanism. In a clean Sage type:
sage: E = FiniteEnumeratedSet([ GF(97)(i) for i in [1,2,3,4,5,6]]); type(E[0]) <type 'sage.rings.finite_rings.integer_mod.IntegerMod_int'> Restart Sage and type instead sage: E = FiniteEnumeratedSet([1,2,3,4,5,6]) sage: type(E[0]) <type 'sage.rings.integer.Integer'> sage: E = FiniteEnumeratedSet([ GF(97)(i) for i in [1,2,3,4,5,6]]); type(E[0]) <type 'sage.rings.integer.Integer'> Many variations of this theme seem possible. This was Sage 7.5.beta0. Can someone knowledgeable help find the root cause and possible other places the bug could appear?
