Hmm, that's pretty broken all right, but it was broken before too.
According to Table 38.11, there are "ten support functions, three of
which are optional". So there have been repeated documentation
failures in this area. I notice that the two lists don't agree
on what the "equal" support function is called, either.
Will fix, thanks for noticing!
