yloop/ YLOOP: Portable implementation of the Yale LOOP
This directory contains five different implementations of Loop
macros. The mit/, cmu/ and symbolics/ directories contain various
implementations of "the" Loop macro, as discussed in the various
editions of CLtL and the draft ANSI Common Lisp specification.
The MIT implementation is from the CLtL1 era. The CMU implementation
conforms to CLtL2, but is slightly buggy. The Symbolics
implementation is an updated (1991) version of the MIT Loop macro. It
claims ANSI Loop conformance, and includes a test suite.
In addition, there is SLOOP and YLOOP. SLOOP is William Schelter's
loop macro (doesn't implement the CLtL specs). YLOOP is Frank Ritter
and Jim Panagos' implementation of the Yale loop macro described in
McDermont, Charniak and Riesbeck's AI programming book.
