Rationalized error handling: if low-level tactic (depth_tac) cannot accept the
goal then it raises exception TRANS. Top-level tactics (blast_tac)
generate warnings and then fail immediately.
berghofe [Mon, 17 Nov 1997 09:52:20 +0100] rev 4232
Tuned function mk_cntxt_splitthm.
Fixed bug which caused split_tac to fail when
(Const ("splitconst", ...) $ ...) was of function type.
nipkow [Sun, 16 Nov 1997 16:18:31 +0100] rev 4231
Removed
"(ALL x:f``A. P x) = (ALL x:A. P(f x))",
"(EX x:f``A. P x) = (EX x:A. P(f x))",
again, because they were already there and added
"(UN x:f``A. B x) = (UN a:A. B(f a))"
"(INT x:f``A. B x) = (INT a:A. B(f a))"
instead.
nipkow [Sat, 15 Nov 1997 18:41:06 +0100] rev 4230
Redesigned the decision procedures for (Abelian) groups and commutative rings.
