I'm not sure what you mean. Can you please give an example?

Sure, but even list has copy().  I meant settable property on the generator not on the generated permutation.

Thanks :)

Settable properties are a no-go because I wanted permutation spaces to be immutable. Since the cost of creating a new space is nil (permutations are created on-demand, not on space creation) there isn't a reason to mutate an existing space.

I don't think using a copy() method to would be very nice. But I guess it's a matter of taste.

Looks great!

Why did you go with "get_rapplied", "unrapplied", etc. instead of having a copy() method and using settable properties?

Hi guys,

I just wanted to give an update on this: I just released my own code that does this to PyPI: https://pypi.python.org/pypi/combi

I'll email you if/when it's released :)

I really like this and hope that it eventually makes it into the stdlib.  It's also a good argument for your other suggestion whereby some of the itertools to return Iterables rather than Iterators like range does.

I'm probably going to implement it in my python_toolbox package. I already implemented 30% and it's really cool. It's at the point where I doubt that I want it in the stdlib because I've gotten so much awesome functionality into it and I'd hate to (a) have 80% of it stripped and (b) have the class names changed to be non-Pythonic :)

At the least, this (a function for getting a specific permutation by
lexicographical-order index) could make a nice cookbook recipe.
