Is this much of the timeline accurate ? Can anyone fill in some
of the holes ?
V1.0 DECUS C (PDT-11/150, RT-11 V?.?), inspired by MacLisp ?
V1.1 1983. Ported to K&R, placed in the PD and submitted to
DECUS, BCS, SIG/M.
V1.2 Renamed things to Common Lisp usage; Byte article; CP/M
V1.4 Death to 8-bit machines.
V1.5 ? (I found a CP/M binary for a "tiny XLISP" once.)
V1.7 Macs, PCs, etal.
V2.1 Almy ?
The current version of XScheme is 0.28. I'm working on 0.41, but it
will probably never be released because it's likely to turn into
XLISP 3.0. Unfortunately, I can't really release it yet because it
doesn't support many of the special forms that even XLISP 1.7 supported.
Conspicuous things that are missing are unwind-protect, catch/throw,
block/return-from, tagbody/go. I suppose I should get those added
before I subject the world to this latest hack. Also, XLISP 3.0
currently supports only a single namespace. It is really more like
XLISP 1.7 and XScheme than XLISP 2.0 or 2.1. It does have packages and
multiple values though.
