That would be irrelevant in most of the cases where I would use it -
typically sorting short lists or dicts where the overhead is

For little standalone scripts it gets a bit tedious to write this again

but I'm glad that it's there.  I'd say list.sorted (or whatever it gets
called) has at least as much claim to exist.
