I have a request for hacker news, in remembering Tom Lord: do you have any of his code lying around? It's hard to find. In addition to GNU arch, I know he once worked on these things:

* a c library called hackerlab

* a Scheme implementation called Pika Scheme

* a regular expression library called rx (may have been renamed to rgx)

* an embeddable VM called Furth

* a graph reduction engine/functional language runtime of some sort
