I'm looking for either the original (not twisted to fit >on PC-Scheme or MIT-Scheme) from Dyvbig [sorry about that] or a >version no quite so dense. Any ideas? I have made three implementations of extend-syntax available on iuvax.cs.indiana.edu for anonymous ftp. The files are: pub/extend-syntax.ss: Chez Scheme source code for extend-syntax pub/mitscheme-extend-syntax.ss: MITScheme compatible version pub/simple-extend.ss: simpler version The first two are certainly dense. The third is much simpler, though the file I found it in was three years old so it may be somewhat out of date. The mitscheme version is a port of a slightly older version of the Chez Scheme source code that didn't handle quasiquote within "with" clauses properly. If someone will send me current versions for MacScheme or PCScheme, I will be happy to make them available for ftp access as well. Kent Dybvig R.
