Huh? I was certain you wanted to use comparison function to get
flexibility, but by hard-wiring < to the code you'll lose that.
One might want to have the list ordered by some other property,
e.g. from largest element to smallest, or by tuple's second element.
Someone might want to put the same objects in several containers, and
the elements would be sorted differently in each container.

You could just add "less than" as a default behaviour
def __init__ (self, comparator=operator.lt):
