Greetings! Am looking for some general advice. Consider the most pathological case, where the user redefines some system function that is inescapable in the top level loop:
(trace format) or (defun read (&rest r) nil) As far as I can tell, there is no way to construct a generalized 'heap-undo' operation, so perhaps what we want here is 1) some emergency immutable code to process one command, or 2) and endless error loop (without abort) in the error handler (i.e. we don't wish to handle this case within lisp), 3) make these functions immutable 4) capture the original definitions in lexical gensyms, and reset on unrecoverable error. Advice?
