I was thinking of generalizing this so that the parser would pass on to the
bytecompiler (and then to the execution engine, whatever that may be) that
an add-on piece was used.
If the execution engine's really a perl->Java translator, the info could be
used to load in some sort of extra code or library. If the execution
engine's a targeted bytecode saver, it could warn that the extras aren't
available. If the execution engine's just the execution engine then, well,
presumably it'd load in the code. :)
