2012-10-03 wenzelm 2012-10-03 tuned;

2012-03-19 wenzelm 2012-03-19 clarified Binding.name_of vs Name_Space.base_name vs Variable.check_name (see also 9bd8d4addd6e, 3305f573294e);
2012-03-18 wenzelm 2012-03-18 maintain generic context naming in structure Name_Space (NB: empty = default_naming, init = local_naming); more explicit Context.generic for Name_Space.declare/define and derivatives (NB: naming changed after Proof_Context.init_global); prefer Context.pretty in low-level operations of structure Sorts/Type (defer full Syntax.init_pretty until error output); simplified signatures;
2012-03-11 wenzelm 2012-03-11 more direct Name_Space.defined_entry; tuned Variable.export_inst: avoid keeping full contexts within the gen_fixesT closure (NB: locale infrastructure stores morphisms persistently);

2011-06-09 wenzelm 2011-06-09 simplified Name.variant -- discontinued builtin fold_map;
2011-04-27 wenzelm 2011-04-27 clarified Variable.focus vs. Variable.focus_cterm -- eliminated clone;
2011-04-27 wenzelm 2011-04-27 tuned signature -- eliminated odd comment;
2011-04-27 wenzelm 2011-04-27 more informative markup for fixed variables (via name space entry); uniform markup for undeclared entities; tuned;

2010-09-12 wenzelm 2010-09-12 load type_infer.ML later -- proper context for Type_Infer.infer_types; renamed Type_Infer.polymorphicT to Type.mark_polymorphic;
2010-08-27 wenzelm 2010-08-27 more careful treatment of context visibility flag wrt. spurious warnings;
2010-05-27 wenzelm 2010-05-27 renamed structure TypeInfer to Type_Infer, keeping the old name as legacy alias for some time;
2010-05-04 wenzelm 2010-05-04 simplified/unified fundamental operations on types/terms/proofterms -- prefer Same.operation over "option" variant;
2010-05-03 wenzelm 2010-05-03 renamed ProofContext.init to ProofContext.init_global to emphasize that this is not the real thing;
2010-04-30 wenzelm 2010-04-30 renamed Variable.thm_context to Variable.global_thm_context to emphasize that this is not the real thing;
