Re: M-x elp-instrument-package RET RET makes emacs unusable

[Richard Stallman]

    Yes, emacs -q and instrument `if', lot of things gets very confused
    (try C-x C-f or C-h f).  Debugging this is beyond my lisp knowledge,
    and I'm also not sure if this is even worth trying to fix if it can't

I think it isn't worth worrying about.  Lisp gives you lots of ways to
hang yourself, and there is no sense trying to block them unless they
are easy to blunder into.
