I notice the following paragraph, vintage late May, in
pdd23_exceptions.pod:
A C<.begin_eh> directive marks the beginning of a span of
opcodes which the programmer expects to throw an exception. If
an exception occurs in the execution of the given opcode span,
Parrot will transfer control to I<LABEL>.
I assume this means that you intend to replace the current methodology
of searching for an Exception_Handler object on the control stack when
an error is thrown with a search through sub metadata. How do you
envision this interacting with C<pushaction>, e.g.? Currently, it is
straightforward for find_exception_handler to DTRT WRT other control
stack entries. Would the metadata also contain information about
C<pushaction> and such?

P.S. FWIW, I am asking now because I have begun to work again on
dynamic binding -- which of course makes this problem worse.
