First issue caught by #7921:
{{{
sage: A2 = WeylCharacterRing(['A',2])
sage: a2 = WeightRing(A2)
sage: TestSuite(a2).run()
Failure in _test_element_pickling:
Traceback (most recent call last):
...
AssertionError: 2*a2(0,0,0) != 2*a2(0,0,0)
}}}
Indeed:
{{{
sage: x = a2.an_element()
sage: x == loads(dumps(x))
False
}}}
I assume that this is an issue in equality test. This should be fixed for
free when WeighRing's will use CombinatorialFreeModules
and categories.
