Feature or enhancement

The random.sample function takes a k argument, I want to make it default to the length of the sequence.

Pitch

It would make a copy-shuffle (as opposed to the in-place shuffle done by random.shuffle) just as simple as one function call. It would also allow easier of random.sample in a functional programming fashion, by avoiding the need to create a variable containing the population variable prior to calling the function.
In other words, random.sample would be to random.shuffle what sorted is to str.sort.
