For what it's worth, I don't agree with the rationale. The debugger
should work on all syntactically correct defuns. If left parens in the
left margin are forbidden in emacs lisp, then I expect a syntax error
during normal evaluation.
At minimum, the debugger should detect this situation, rather than
silently doing the wrong thing.
