I'm not following this thread. Just happened to
read your initial statement, which sounds like
you want to repeat invoking a function until it
returns nil or non-nil.
If so, Emacs already gives you that:
(`*-success' is similar).
_____ And `C-h v' tells you this ____
run-hook-with-args-until-failure is a built-in function in ‘C source
(run-hook-with-args-until-failure HOOK &rest ARGS)
Run HOOK with the specified arguments ARGS.
HOOK should be a symbol, a hook variable. The value of HOOK
may be nil, a function, or a list of functions. Call each
function in order with arguments ARGS, stopping at the first
one that returns nil, and return nil. Otherwise (if all functions
return non-nil, or if there are no functions to call), return non-nil
(do not rely on the precise return value in this case).
Do not use `make-local-variable' to make a hook variable buffer-local.
Instead, use `add-hook' and specify t for the LOCAL argument.
