Idempotent is a ten-dollar word. Can we find something that average
people wouldn't need to consult a dictionary to understand?
I disagree that we should dumb things down when the word means exactly what
we want and based on the rest of this thread is the only word or word
cluster that carries the desired meaning.
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 ...
I have heard idempotent used several times by our folks, and I didn't
know what it meant either. I figured it was a "strong item". ;-) I
just looked it up.
The math term used in Hungarian for idempotent is mirror translated
to "leave it in place". The term also has a slang usage for beating somebody
up. ;-)
