I think that you are right - I screwed up by nor reading the first sentence
carefully enough.

Yes, I think that it is in that it excludes procedures marked as elemental that
are not, in fact, elemental.

I have taken a brief look at making a runtime version of this error and have
recoiled in horror; the combination of simplification and separate translation
of intrinsic procedures leads me to believe that the best course of action
would be to accept Steve's patch and change the error to a warning.
