This is of course then not really true in a wider sense, as an example from "T J" shows: a = 1 a += IGNORE(3) # -> a := a + IGNORE(3) # -> a := IGNORE(4) # -> a == IGNORE(1) which is different from a = 1 + IGNORE(3) # -> a == IGNORE(4) Damn, it seemed so good. Probably anything expect destructive assignment leads to problems like this with propagating special values. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
