Excellent question.

Thanks, but I was hoping for a somewhat more specific answer.

FYI, due to prodding by yours truly, and kudos to them, Lispworks has re-introduced the API in 6.x.

This recently! And have they found significant issues while they were at it?

Franz seems to have found some and changed a few of the return values but I
fail to understand why they did it in a way that is not a superset of the CLTL2 text.
Any clue?
