I rather like the convention used elsewhere in Python of naming in-place operations with present tense imperative verbs, and out-of-place operations with past participles. So you have sort/sorted, reverse/reversed, etc. Here this would suggest we name these two operations as either shuffle() and shuffled(), or permute() and permuted(). -n
