I suggest you use an existing language that you can extend with your
own primitives, written in a language of your choice. Systems that
come to mind are UNTIL, a Forth system built for exactly this purpose,
and a lot of Scheme systems like Aubrey Jaffer's SCM or George
Carrette's SIOD.


You can find UNTIL and a lot of other Forth systems at the Forth
Interest Group:


    <URL:http://www.forth.org/>


You can find something known as the Scheme Underground at:


    <URL:http://www.ai.mit.edu/projects/su/su.html>


They use yet another Scheme implementation, known as Scheme48.


I apologize for not having URL's handy for SCM and SIOD. Jaffer is
employed at MIT, however, so it's somewhere around there.


Other languages that is also rather easy to use as extension languages
are Python and Perl. See <URL:http://www.python.org/>.
