I have no better idea but I think it can be handled by 'catch
exception', but I don't think guile/clisp/emacs have same procedure
named 'catch' or else.

Here's a dilemma, unless guile/clisp/emacs have the same
checker-procedure with same name and definition, you have no promise to
check it under different language environment. The best way is
prepossess which is portable.
Maybe there's better idea I didn't know?
Thanks!
