[issue35117] set.discard should return True or False based on if element existed.

[tzickel]

New submission from tzickel <icebreak at yahoo.com>:

Sometimes you want to do something based on if the item existed before removal, so instead of checking if it exists, then removing and doing something, if would be nice to make the function return True or False based on if the element existed.
