I heard from Arthur that it would be helpful if someone could provide sample implementations for SRFIs 142, 143, and 144.

I wrote up one for 142 today -- portable, depending only on (scheme base) and (srfi 121) (because the spec requires it). Comes with a test script. Ran it on my own system plus chibi.

I don't want to clutter up this mailing list with code or attachments - where should I put it?
