[TUHS] Lisp is a family quarrel

Tim Bradshaw scripsit: As I said, it allows you to adjust to a mismatch: a keyboard that types lower case by default, software that rejects lower case. "Do you know the saying, Karhide is not a nation but a family quarrel?" I haven't, and suspect that Estraven made it up; it has his stamp. --Le Guin, _The Left Hand of Darkness_ Lisp, too, is a family quarrel. Scheme is even more so than Common Lisp; CL is a language, but Scheme is a family of languages, perhaps 80 of them. The minimalist R5RS standard of 1998 was case-folding, like all standards before it, but perhaps half of all implementations ignored this and were case-sensitive. In practice, case-folding implementations folded to lower case, and where case was not folded, the standard identifiers were lower case. The latter position is a feature of the case-sensitive R6RS (2007) and R7RS-small (2013) standards. At present, case-sensitivity dominates in the 40+ implementations that I use for test purposes by about two to one. -- John Cowan http://www.ccil.org/~cowan cowan(a)ccil.org After fixing the Y2K bug in an application: WELCOME TO <censored> DATE: MONDAK, JANUARK 1, 1900
