Well, yes and no - you *can* use the metamethod to set a custom
behaviour for the % operator, but only for tables and full userdata -
you *can't* use it to replace the standard behaviour for numbers:

1
...so, while technically it is a change from math.mod(), it would
really only be in cases where math.mod() would throw an error because
it was given invalid arguments.
