2014-10-14 ago tuned signature;
2014-07-04 ago insist in explicit overloading;
2014-03-12 ago more explicit Sign.change_check -- detect structural mistakes where they emerge, not at later theory merges;

2011-04-20 ago added Theory.nodes_of convenience;
2011-04-18 ago recovered Theory.check_def: full name needs to be determined from background thy, not auxiliary ctxt (broken in 774df7c59508, caused Nitpick.all_axioms_of to produce bad results);
2011-04-18 ago pass plain Proof.context for pretty printing;
2011-04-18 ago pass plain Proof.context for pretty printing;
