does toMutableList on a mutable list copy that list?
Otherwise, how do you copy a list? I could use the ArrayList constructor but if there is a kotlin way of copying a list I'd rather do that.

toMutableList actually calls ArrayList(this)

Good to know.
I wasn't sure if there was some check on this to see if it was already a mutable list before copying it.
