wenzelm [Sat, 08 Nov 2014 16:42:04 +0100] rev 58947
avoid slow metis proof;
wenzelm [Sat, 08 Nov 2014 16:35:24 +0100] rev 58946
proper Envir.norm_type for result of Unify.unifiers (amending 479832ff2d29 from 20 years ago);
wenzelm [Sat, 08 Nov 2014 15:45:00 +0100] rev 58945
tuned;
wenzelm [Sat, 08 Nov 2014 15:44:41 +0100] rev 58944
updated some sledgehammer proofs -- much faster;
wenzelm [Sat, 08 Nov 2014 15:40:29 +0100] rev 58943
updated sledgehammer proof after breakdown of metis (exception Type.TUNIFY);
wenzelm [Sat, 08 Nov 2014 15:01:05 +0100] rev 58942
recovered type matching, which was broken in 8a765db7e0f8 (see also 8a765db7e0f8, 2db1d3d2ed54);
NB: "match" operates on direct substitution without variable chasing, in contrast to "unify" (and Unify.matches!) which work on cascaded env;
wenzelm [Sat, 08 Nov 2014 12:15:40 +0100] rev 58941
more direct type equality;
haftmann [Sat, 08 Nov 2014 09:19:57 +0100] rev 58940
reverted commit accident from 994fe0ba8335
haftmann [Sat, 08 Nov 2014 09:16:47 +0100] rev 58939
less space-wasting serialization setup: highest cell of array has been unused so far
wenzelm [Fri, 07 Nov 2014 23:35:13 +0100] rev 58938
tuned outline;
