I disagree.  I think people write interpreters all the time; they just
don't realize they're writing them, so they crank out lame, ad hoc
interpreters that don't do a whole lot.

One project I worked on actually had 4-5 *different* interpreters in
it, just because as many different programmers decided to invent their
own, incompatible, configuration file formats.  And this is a project
that already had its own full-blown, turing-complete scripting
language that, appearently, the other programmers either didn't know
or like well enough to use for their own purposes (not that I blame
them; it was a really crappy language).

My experience may be atypical (I work on video games), but I can't
think of too many useful programs that don't, at least, have some
configuration or document files that they interpret.

Best wishes,
