So let-bind forward-sexp-function around any calls where you think that
might happen.
forward-sexp is user in 100s of places in lisp/.

Hi,

as `forward-sexp-function' might be set by users, `forward-sexp' is susceptible to fail when built into a program - which executes then set new binding.
Just came across that mistake.

Suggest a warning in it's docstring, saying something like: "Don't use..."
While pointing at core-function `scan-sexp' resp. `forward-sexp-function'.

Thanks,

Andreas
