Modified proofs for new form of 'split'.
lcp [Thu, 04 May 1995 02:00:38 +0200] rev 1106
Added pattern-matching code from CHOL/Prod.thy. Changed
definitions so that split is now defined in terms of fst, snd. Now split is
polymorphic. Deleted fsplit, as split(...)::o gives a similar effect -- NOT
identical though, as fsplit(P,z) implied that z was a pair, while split(P,z)
means only P(fst(z),snd(z)).
lcp [Wed, 03 May 1995 17:38:27 +0200] rev 1105
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 17:30:36 +0200] rev 1104
Changed to use split instead of fsplit. The weakening of fsplitE appears not
to affect existing proofs.
lcp [Wed, 03 May 1995 17:22:18 +0200] rev 1103
prove_case_equation now calls uses meta_eq_to_obj_eq to cope
with new form of 'split'. Tried calling simp_tac instead of using resolution
with trans, but it was significantly slower: 98.3 secs instead of 91.2 secs
for ex/Enum.

fixed bug in thy_unchanged that occurred when the .thy file was changed
but the .ML file hadn't been read before;
tmpfile is now deleted immediatly after reading the .thy file in use_thy
