yeah.. that would work.  If it works on my Emacs install it would probably work
on all of them :)

agreed.

Smalltalk style environments really work out well.  There is only a slight
lag.  They have a HIGH level of development though.  They need an integrated
incrementalk compiler which ties into your database index.

We couldn't do this emacs without a LOT of work.  jde-docindex does this but you
do have the burden of keeping indexes up-to-date.  I am working on a
differential compiler for it so maybe it will get better in the future.

Emacs 21 supports dynamic font widths.  This won't work... on '21

It is because you can't do it! :)... I will buy the first person a beer if they
figure out how to get the X/Y coords of (point) .... :)

Dynamic face sizes really complicate things.  A lot of functions don't take into
account the menu-bar, tool-bar, fringe, display property, glyphs, overlays, etc.
There is a C function for this... forget what it is called... but it isn't
exported to lisp yet.
