How small do we really need to go?  Are we looking at implementing Perl for
microcontrollers, or are we only worrying about Perl for PDAs?  The
difference is that PDAs are now shipping with much greater amounts of memory
than they first started with.  For example, my 2-year-old Palm III only had
2M of RAM, which isn't much RAM when perl consumes around 1M or so.  But my
new Handspring Visor comes with 8M, which looks much more reasonable for
perl (and Perl).

On the other hand, microcontrollers still don't have a lot of RAM, at least
as compared to PDAs.  I think there are a number of microcontrollers sold
today that don't ship with even 1M of RAM or ROM, although there are
multi-Meg microcontrollers now.

And on the gripping hand -- well, that's Larry's, anyway.  Just my $0.02US.
