I see, didn't know that. Of course, the reason that IDEs follow this is the underlying convention that a) Properties are blazingly fast to compute. b) Properties don't throw exceptions. Neither of which are satisfied for Matrix.I. If B is a 1000x1000 matrix over ZZ(x), then B.I.roo<Tab> is going to hang your IDE for a while :-) Best, Johan -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
