Hmmm, LEAVE refers to "compilation semantics" needing "loop control
parameters".  Yet DO indicates that there are "loop control parameters" for
the "interpretation semantics".  Another note, the compiling stack for DO is
backwards.

Yes, but how?   It would be nice to access the index from called words, too.
