The "foo partitions bar" message is triggered by constructs like this:
matchdeclare (xx, foo_p, yy, not_foo_p);
foo_p (e) := not atom(e) and op(e) = 'foo;
not_foo_p (e) := not foo_p (e);
tellsimpafter (xx*yy, FOO (xx, yy));
=> yy xx partitions `product'
Since the predicates foo_p and not_foo_p are exhaustive and
mutually exclusive, this is really a best-case scenario.
The rules I write usually have such predicates (because they make
life easier) so they usually get the warning message.
