I'm the wrong one to ask about this -- my elisp only works because of
liberal sprinklings of pixie dust -- but if you read the elisp manual on
macros, and keep in mind that backquoting works in contexts other than
that of macros, you'll be most of the way there. What I used in this
tiny example (plus the ,@ form for splicing lists) is pretty much all
there is to it, though the ramifications do get complicated…

Good luck!
