I think, if you're willing to forego string eval (which is more prevailant then you think: file-do is a form of string-eval, require is a form of file-do, and use is a form of require -- and I'm extending it to go as far as compilation of the original input program), you can cut down on the size of the perl interpreter significatly... at the expense of destroying the ablity to develop perl from the PDA, which was probably part of the point of the exercise.

You'd have to do the ripping-out work, create a perlio OS layer to treat records in the Palm DB as files, and create a perl bytecode loader in XS/C, rather then Perl, and tie it together. It's hardly insignificant, but should be doable.

My devel box is down, so I can't even give you very loose numbers, unfornatly.


Confession: It does an Immortal Body good.
