lcp [Wed, 03 May 1995 14:54:43 +0200] rev 1096
Modified proofs for (q)split, fst, snd for new
definitions. The rule f(q)splitE is now called (q)splitE and is weaker than
before. The rule '(q)split' is now a meta-equality; this required modifying
all proofs involving e.g. split RS trans.
lcp [Wed, 03 May 1995 14:41:36 +0200] rev 1095
Changed some definitions and proofs to use pattern-matching.
lcp [Wed, 03 May 1995 14:27:51 +0200] rev 1094
Patterns can now be let-bound
lcp [Wed, 03 May 1995 14:17:01 +0200] rev 1093
Changed to use split instead of fsplit. The weakening of fsplitE appears not
to affect existing proofs.
lcp [Wed, 03 May 1995 14:03:19 +0200] rev 1092
Changed some definitions and proofs to use pattern-matching.
lcp [Wed, 03 May 1995 13:55:05 +0200] rev 1091
Changed some definitions and proofs to use pattern-matching.
