That's obviously an error -- since it contains code from lisp.el --
probably due to Emacs regressions breaking my context-dependent
settings, which I didn't spot in that case.  I'll fix the notice when I
get a chance.

Obviously it was meant to be in Emacs.  It would have been, with other
abstractions, if I'd got round to it when I was a maintainer.  However
it was rejected previously and expurgated from python.el.  There's no
point in using it just for Python.

Indeed, in general, but that was a mistake.  You can use the sym-comp
code if it's now acceptable for some reason.

It would be better if contributions weren't rejected and then either
used or reimplemented by someone else years later, or broken randomly,
or just left to linger in CVS for years without even accepting bug
reports/fixes from people who wrote them.
