In some circumstances, it's not "more complex", it's "impossible".
For example, something like
-- don't do this for real :-)
repeat forever
ask "What should I do next?"
if it = "quit" then exit repeat
put it into tNextHandler
do "tNextHandler"
next repeat
However, there are cases less egregious than this which can hide the
handler name pretty thoroughly, so you need to decide just *how* far
dead a handler needs to be in order to remove it :-)

Hi Phil,
I assume you're trying to find handlers that are not referenced by any
other handlers? I started on a stack a while back to do the reverse of
that - cross reference where handlers are called from but it would show you
which ones are not called from anywhere.
I'll have to search round for it because I kinda left it alone in favor of
doing other things but let me know if this is what you're looking for and
I'll see if I can find it and see what state it's in.

Hi folks -
Does anyone have a dead handler detector they would like to share? I
looked in RevOnline but didn't find anything.
It seems I'm always working on old code that contains handlers that have
been superseded by other handlers. I would like an easy way to find those
now-unused handlers and remove them.
I realize the task of detecting dead handlers is conceptually simple but
more complex when it comes to implementation. Still, maybe you have built
such a thing that you wouldn't mind sharing.
Happy New Year! (Is it too early to say that?)
