I don't get your point at all. How can empty or not implemented method "provide" anything ? I am totally free to define t.LeADeEEIIiiing_CoeffICIENT() somewhere, even if some t.leading_coefficient() method that raises an exception anyway exists already. Why isn't "abs" defined in SageObject directly, then ? It creates a method where it has no meaning, and can only be used to raise exceptions and confuse beginners. If there is a point to all that, I don't get it.... O_o Nathann -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
