One thing that PostScript has over Lisp is that it's very easy to do a
Forth-style threaded implementation.  Lisp storage allocation in particular
can be much more complex, and with only so much RAM to play with, a
stack-based threaded language can give you more "bang for the buck".
It's also marginally easier to generate from a program (unless that program
is written in Lisp :-)), which is nice for things like output drivers,
emulators, and so on.

Does anyone know what ever happened to LispScript?  It was a baby Lisp
interpreter that compiled into normal PostScript.
