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:
@operator.itemgetter(1)
@min
@apply
def closest_object():
for x in xrange(board_width)
for y in xrange(board_height):
try:
entity = board.get_entity(x, y)
except EntityNotFound:
pass
else:
yield distance(player.pos, entity.pos), entity
Please don't kill me.
