A conserative garbage collector was an intrinsic part of Interlisp-D. All references from the heap were precise, but the stack was scanned conservatively (in order to make the processing of unboxed floats cheap). The Quintus Prolog garbage collector had a similar problem with floats, and took the conservative route. These were not after-the-fact off-the-shelf collectors for an uncooperative language, but special purpose collectors co-designed with the implementation of languages designed for garbage collection. This kind of conservative collector worked very well indeed in practice. -- Mixed Member Proportional---a *great* way to vote! Richard A. O'Keefe; http://www.cs.rmit.edu.au/%7Eok; RMIT Comp.Sci.
