There's "Object Layer" (is there a pun in there?) from Xerox, which
is a Prolog pre-processor for SICStus & QUINTUS. I only have an e-mail
address now...

    fromherz@parc.xerox.com

Very Smalltalkish as I recall.

I've developed my own pre-processor for a Prolog interpretor I once
wrote and had lying around, based more or less around a C++ syntax.
I was mainly interested in GUI scripting & rapid protyping and it (i.e.
an interpreted OO-Prolog) seems to be a natural for that. Based around
the wxWindows free PIGUI (platform independant GUI) it is portable
(so far BC++ 3.1 on Windows & Cfront on Suns/XView or Motif, sorry but
g++ craps out so no Linux) and now in alpha testing. I'll be happy to
make it available soon to adventurous souls. I've tried to keep it very
simple while still being useful... more along the lines of "Prolog with
Classes" than Prolog++.

I don't know how much interest there is out there for this kind of stuff,
i've been working pretty much in the dark on this. Anyway... enuff of
that.





Regards.
