TypeError. You can't slice None.
If you're going to be taking copies on entry, you might as well use
def __init__( self, myList= ):
self.myList = myList[:]
However, copying is inefficient. Not a problem in most cases, but
I've got a lot of objects to initialise. (This is for a GA). Solution: use
"myList or ", but carefully.
