Hello, I found out that we have problems with elements of ZZ(x):
sage: x = polygen(ZZ) sage: p = (-1)/(-x) sage: q = 1/x sage: p -1/-x sage: q 1/x sage: p == q True sage: hash(p) == hash(q) False One good challenge for the bug days. If no ticket is yet open about it, I will do that shortly. Vincent -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
