"prep_const" now calls compress_type to ensure sharing among
types of constants in theories.
paulson [Fri, 22 Dec 1995 10:26:57 +0100] rev 1413
"prepare_proof" has been simplified because
rewrite_rule and rewrite_goals_rule check for empty lists.
The list of premises is *not* passed to Thm.compress; this was tried, but
the potential storage gains seemed not to justify the cpu time required.
paulson [Fri, 22 Dec 1995 10:19:55 +0100] rev 1412
Now "standard" compresses theorems (for sharing).
Also, rewrite_rule and rewrite_goals_rule check for the empty list of
rewrites and do nothing in that case.
paulson [Fri, 22 Dec 1995 10:11:35 +0100] rev 1411
Now loads symtab.ML before term.ML. Functor
> SymtabFun has been changed to the structure Symtab.

fixedpoint definition.

paulson [Fri, 08 Dec 1995 10:39:52 +0100] rev 1394
New function read_cterms is a combination of read_def_cterm and
read_cterm. It reads and simultaneously type-checks a list of strings.
cterm_of no longer catches exception TYPE; instead it must be caught later on
and a message printed using Sign.exn_type_msg. More informative messages can
be printed this way.
paulson [Fri, 08 Dec 1995 10:36:36 +0100] rev 1393
exports exn_type_msg for error messages. Calls new infer_types.
Improved comments.
paulson [Fri, 08 Dec 1995 10:35:48 +0100] rev 1392
infer_types now takes a term list and a type list as argument. It
is defined using the new function infer_terms. Error messages and
comments also improved.
