Me too, though the comparison on my part was to using a "code is data"
language like Lisp.  Another approach would be to have an embeddable
extension language in a library, which for the GNU project means Guile,
a Scheme interpreter that has gotten quite large and powerful.  The rest
of the world seems to have settled on Lua or sometimes Python or
Javascript for this purpose.  Lua has language warts but is a small and
clean implementation that's nice for embedding.  Python is a nicer
language but its main implementation is rather clumsy IMHO.  And
Javascript is, well, Javascript.

I'm partial to the Scheme/Lisp approach myself and I think Guile is an
admirable Scheme implementation, but it's become closer to a full
featured standalone system, while for embedding purposes I'd prefer
something smaller.
