HOL,ZF/IMP/Com.thy: tightening precedences to eliminate syntactic ambiguities.
constructor ";" now yields a low precedence; the reduction relations are
now more like infixes.
lcp [Fri, 21 Oct 1994 09:58:05 +0100] rev 652
ZF/intr_elim/elim_rls: now includes Pair_inject, since coinductive
definitions may involve ordinary pairs. (HOL/intr_elim does not require
this change)
lcp [Fri, 21 Oct 1994 09:53:38 +0100] rev 651
Pure/Unify/IMPROVING "CLEANING" OF FLEX-FLEX PAIRS: Old code would refuse
to simplfy %x y.?a(x) =?= %x y.?b(f(?c(y), y)) because it found the flexible
path to y before the rigid path. New code simplifies this to
%x.?a(x) =?= %x.?d, eliminating ?a.
Pure/Unify/rigid_bound: preliminary check for rigid paths to the banned
bound variables
Pure/Unify/change_bnos: any occurrences of the banned bound variables must
now be flexible, causing abandonment of the "cleaning"
lcp [Fri, 21 Oct 1994 09:51:01 +0100] rev 650
LK/hardquant/37: deleted call to flexflex_tac: no longer needed

LCF/LCF.thy: the constant VOID had mixfix syntax "()" !! Added quotes.
lcp [Fri, 21 Oct 1994 09:35:24 +0100] rev 648
FOLP/IFOLP.thy: tightening precedences to eliminate syntactic ambiguities.
Now proof objects have high precedences. Eliminates ambiguity in a=b:P
being parsed as (a=b):P.

Pure/tctical/suppress_tracing: new; can now switch tracing off until the
next tactical call. There is no good way of doing this because of
backtracking.
