Or func+args in some new magic type, so a subr can return either a
value or a new place to goto.

I was wanting `catch' to do a tail call to its handler so the handler
could recurse to continue on the rest of some data.  `catch' would be
a case of either returning a value (from the body) or the handler to
jump to.
