I should add that I wasn't *really* expecting the very first cut of
this to "Just Work(tm)", although with something coming from you guys
it was worth a try... :-) It was just a non-scientific experiment
on my part.

It would also enable Squeak as a light-weight scripting engine.
Anyway, it's good to hear that this is considered a good thing by
Squeak central, even if it's not a priority right now. Would you be
able to provide a little support for others implementing something
along these lines or do you think it's hopeless? I would certainly
be willing to burn my Squeak-cycles on something like this while I
wait for a pronouncement on EncodingFilters/MorphicPostscipt (and
afterwards as well).
