I'm sorry; which is your problem? [ruby-talk:85791]?

"resume" won't work well unless both your code and the user code know
each other (the user code must care that raise might resume; your code
must know how to fix up the exception cause). In that case, I think
you can make "retry" work, otherwise you can't make them work well
anyway.
