I'm not quite convinced that it means *exactly* what we want. The
dictionary definition, according to my laptop's dictionary, is "denoting
an element of a set that is unchanged in value when multiplied or
otherwise operated on by itself". I'm well aware that computer people
often use it to mean "an operation that doesn't change the system state
if the state is already what's wanted", but I think that's probably an
abuse of the mathematical usage. And in any case, I'm not sure that
non-hackers would immediately recognize the term, nor be enlightened by
their dictionaries. But ...
