I think this has a lot to do with the "explicit syntax tree" that you build
with LISP programs.  Think about it -- the structure of LISP programs
directly mirrors an equivalent semantic tree built with a traditional
compiler, like C.  As a result, the same types of optimizations that are
possible with languages like C are possible with the likes of LISP too.
Many LISP environments compile to raw assembly language too, though I
somehow doubt elisp does this.

There is little, if anything, preventing this type of optimizability in
Python as well -- I recall a discussion from a friend of mine (Billy
Tanksley) from before I regularly read this newsgroup, indicating a desire
to switch from plain bytecodes to three-operand RISC-like, platform
independent, fixed-width codes.  If memory serves me correctly, it had
something to do with run-time code optimization and efficiency.

Plenty fast enough in my opinion.

If you're going to go this route, then please also consider adding CORBA
interfaces.  Having an editor that is simultaneously scriptable via COM and
CORBA will be very, very useful.

If not COM, then definately CORBA -- ORBs such as OmniORBpy and Fnorb (<--
VERY easy to use, BTW -- highly recommended) are available, and are
reasonably cross-platform, as CORBA is designed to be as independent from
its supporting environment as possible.

I would like to see GTK myself.  Tkinter just "feels" wrong to me for some
reason.

Quite likely we'd have a kick-butt editor that didn't take up 20MB+ of drive
space.  :)
