Interesting--I never thought of xpcall as a try/catch.  However, one
problem in your code is that the "error(err)" in the error handler
doesn't propagate the error but rather causes xpcall to return an
"error in error handling" because many times the caller wants to
suppress *all* errors.  Maybe xpcall should though in some way support
error handlers that propagate errors to better support this usage.
