There are two oddities here.
The first string is, of course, absurd. A fool could see that. It isn't quite as bad as a Prolog example I once saw:
> lessthan(clergyman, avocado).
But it's getting there.
And then there is the justification of the silly function placing with hysterical raisins. This is a common theme in Erlang, actually; hide perfectly simple functions in strange modules that no-one uses, then claim historical reasons when they are unearthed.
