   Allison, if you give me the OK, I'll recast pdd23 in the alternative way I
   had in mind, where:

    * exception handlers are closures,

    * the closures are called _inside_ the dynamic scope where the throw
      occurred,

    * a closure returning without executing C<caught> implies "I didn't handle
          it, try the next handler",
        therefore obviating the "rethrow" opcode.

   PS: "caught" will perhaps be better renamed "handled".

I'm still trying to catch up, but IMHO, this is all to the good.
