min can be a little inconvenient. As soon as anything complicated has
to be done during the min expression, you need to switch to using
something else for sanity's sake. In that vein, I do actually
sometimes use float('inf') (for numbers), or a custom max/min object.


Silly and completely nonserious addendum:

Forgive me, I have spoken in error! min is the one true way, for you
can still do it with a little wrangling, as follows:

    def closest_object():
        for x in xrange(board_width)
            for y in xrange(board_height):
                    entity = board.get_entity(x, y)
                except EntityNotFound:
                    yield distance(player.pos, entity.pos), entity

Please don't kill me.
