That's sort of unfairly dismissive of Postscript, don't you think?
It's a fairly nice programming language (for those who like that sort
of thing), with some really nice geometric and text-formatting
primitives. Don Lancaster uses it to drive robots; even the blue book
contains a primitive text formatter. I've seen an IFS in PostScript;
there's a genetic-algorithm-based picture generator written in
PostScript at; there's a fairly
full-featured text formatter in PostScript at

It has the syntax of FORTH, the type system of Lisp (very roughly), and
Ghostscript has the speed of RScheme or Lua --- it's almost as fast as
FORTH, and is way faster than Perl.

I tend to think it's not a more popular programming language for the
following reasons:
- historically, most PostScript interpreters have been inside of printers
- FORTH's syntax and Lisp's type system are both very strange to Algol

Not that *I've* ever written anything interesting in it.

The power didn't go out on 2000-01-01 either.  :)
