[Chicken-users] Wikipedia
The Wikipedia article on Scheme had been of rather poor quality for some time and I always meant to do something about that. During the past week or so I've given it a pretty severe rewrite, and in doing so I've learned a lot about Scheme, and particularly its history, that I didn't realise I didn't know. http://en.wikipedia.org/wiki/Scheme_(programming_language) Note that the article is very strongly biased toward R5RS. I think this is in keeping with the neutral point of view principle, in which subjects are covered according to their importance. Clearly R5RS is going to be around for a good long time and is the de facto standard for all but a few Scheme implementations, whereas R6RS got off to a very shaky start and hasn't yet gained widespread acceptance among implementers; I've started, but will need a lot more time to complete, a comprehensive history of Scheme, starting with prehistory, the first block structured programming languages and the first Lisps, and eventually coming down to the present-day language. I have a lot of material for this because Geral Jay Sussman and Guy L. Steele have never hidden their pride at having produced such a gem, but it all has to be read through and digested. http://en.wikipedia.org/wiki/History_of_the_Scheme_programming_language I offer this up in the knowledge that others on this list may find it interesting, and of course any help in researching the history would always be welcome. ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
