Sometimes you might have to check the type in library code, but it shouldn't be necessary for the user. You'll have to know about the factory function pattern if you want to read and understand the Sage library code in any case. To find out the name of the class you type in Permutation?? and scroll down. I don't think its a big deal or particularly time-consuming. The surprise factor that a function returns a differently-named class is a lot less than the surprise you get when something that looks like a class constructor call gives you a completely unrelated instance, that is totally at odds with normal Python syntax. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
