puerly -> purely
CASE -> CAS

 -> new dependency that must be propagated to the comment.

I've committed your patch with those two issues fixed, and I've added a
follow-up commit to further fix the dependencies of the comment, which
were already wrong.

Frank, do not hesitate to report about your testing after this patch.
It would be interesting if you could provide some simple test cases to
test the Erlang stuff, so that padawans like me can easily do a simple
testing of whether it still works or not.

Thanks,

Thomas
