[comp.lang.smalltalk] Prolog in Smalltalk

winfwrd@dutrun.UUCP (Paul van der Weerd) (03/28/89)

Digitalk enclosed a Prolog interpreter with their Smalltalk/V package for the 
IBM-PC. Since I'm not an experienced Prolog user, I would like to hear some 
opinions about this particular Prolog implementation. 

Some months ago we left Smalltalk/V and started with the Smalltalk-80 
environment on Macintosh II and Sun-3 (mainly because of source-code 
exchangeability) and right now we are considering converting Prolog-St/V to 
Prolog-St-80 (or has anyone done this already?).

Perhaps we are on the wrong track of importing logic programming into 
Smalltalk and better tools might be available. Any suggestions are welcome.

If you just want to play around and learn alittle, it may be ok;
however, its syntax is non-standard, it does not support even all of
Clocksin and Mellish (C&M) let alone the standard extensions (bag_of,
set_of, member, ...), and it is VERY slow and memory intensive.

Hum, isn't that violation of copyright or intellectual property rights?
