2015-09-24 wenzelm 2015-09-24 more explicit Defs.context: use proper name spaces as far as possible;

2015-09-22 wenzelm 2015-09-22 tuned output;
2015-09-22 wenzelm 2015-09-22 renamed Defs.node to Defs.item; clarified type Defs.item; clarified item_ord for printing;
2015-09-22 wenzelm 2015-09-22 HOL typedef with explicit dependency checks according to Ondrey Kuncar, 07-Jul-2015, 16-Jul-2015, 30-Jul-2015; defs.ML: track dependencies also for type constructors; typedef.ML: add type defined by typedef to dependencies, Abs and Rep now depend on the type; Pure types and typedecls are final -- no dependencies;
2014-11-24 wenzelm 2014-11-24 removed odd remains of structural containment checks, which stem from an older approach (see also 3ad1b289f21b, 3ae3cc4b1eac, 423af2e013b8, bad13b32c0f3, ccd6de95f4a6); de-facto this alternative never occured in practice, but it can lead to non-termination of the check;
2014-07-05 wenzelm 2014-07-05 proper plain_args to ensure that multi-argument overloading cannot escape pattern restriction (despite more liberal structural containment before 3ae3cc4b1eac);
2014-03-11 wenzelm 2014-03-11 minor performance tuning via fast matching filter;
2014-02-17 wenzelm 2014-02-17 more informative error;

2011-04-18 wenzelm 2011-04-18 simplified pretty printing context, which is only required for certain kernel operations; disentangled dependencies of structure Pretty;
2010-03-20 wenzelm 2010-03-20 renamed varify/unvarify operations to varify_global/unvarify_global to emphasize that these only work in a global situation;

2006-06-07 wenzelm 2006-06-07 renamed Type.(un)varifyT to Logic.(un)varifyT; made (un)varify strict wrt. global context -- may use legacy_(un)varify as workaround;
2006-06-02 wenzelm 2006-06-02 merge: always normalize (and check!) reductions;
2006-05-26 wenzelm 2006-05-26 separate checks for acyclic/wellformed;

2006-05-24 wenzelm 2006-05-24 tuned;
2006-05-23 wenzelm 2006-05-23 export plain_args; tuned wellformed, normalize;

2006-05-20 wenzelm 2006-05-20 made smlnj happy;
2006-05-20 wenzelm 2006-05-20 yet another re-implementation: . maintain explicit mapping from unspecified to specified consts (no dependency graph, no termination check, but direct reduction of specifications); . more precise checking of LHS patterns -- specialized patterns (e.g. 'a => 'a instead of general 'a => 'b) impose global restrictions;
2006-05-13 wenzelm 2006-05-13 actually reject malformed defs; added unchecked flag; tuned;
