Okay, the attached changeset changes the error message into saying that
the function is not documented. Now this stuff seems to work just fine
for me.

I do, however, still see one regression: I cannot do

  type @polynomial/set

which used to be possible. The problem is that

  exist ("@polynomial/set")

returns 0 which the new implementation of 'type' cannot handle. So, my
question is: should the above call to 'exist' return something else, or
should the 'type' implementation be changed such that it doesn't depend
on 'exist'?
