But is it really a good idea to codify PVM bytecode as the way to do
introspection?  I'd much rather have a standard library API that
parses a module and gives you a list of variables, functions, classes,
etc., and lets you drill down into the symbol table of each of those.
(I realize more is needed, you need to be able to inspect every
statement too -- that can be done by providing access to an AST.)
