The only one that's skippable is the optimizer, really. I'd planned on
having to pass it some indicator of how aggressive it should be,

Yup. Hence the "replaceable" bit. :) The boxes would all have a fixed and
well-defined interface, and the various streams (syntax tree and bytcode)
would also be well-defined. If you wanted to build an execution box that
instead dumped out java bytecodes, well, sounds like a good plan to me. :)

Might. Hard to say, though if we get them as black boxes at least it'll
make debugging more compartmentalized.
