wenzelm [Thu, 15 Apr 2010 18:09:22 +0200] rev 36153
replaced slightly odd Typedecl.predeclare_constraints by plain declaration of type arguments -- also avoid "recursive" declaration of type constructor, which can cause problems with sequential definitions B.foo = A.foo;
simplified via ProofContext.check_tfree;
wenzelm [Thu, 15 Apr 2010 18:00:21 +0200] rev 36152
get_sort: suppress dummyS from input;
added check_tvar, check_tfree convenience;
tuned;
wenzelm [Thu, 15 Apr 2010 16:58:12 +0200] rev 36151
modernized treatment of sort constraints in specification;
pass-through type variables as usual as (string * sort) internally -- recovers proper sort handling;
wenzelm [Thu, 15 Apr 2010 16:55:49 +0200] rev 36150
typecopy: observe given sort constraints more precisely;
wenzelm [Thu, 15 Apr 2010 15:39:50 +0200] rev 36149
