proof terms for strip_shyps, based on the version by krauss/schropp with some notable differences:
2010-05-04, by wenzelm
simplified/unified fundamental operations on types/terms/proofterms -- prefer Same.operation over "option" variant;
2010-05-04, by wenzelm
renamed Proofterm.freezeT to Proofterm.legacy_freezeT (cf. 88756a5a92fc);
2010-05-04, by wenzelm
specification goal: eliminated redundant Thm.legacy_freezeT -- the goal is properly declared and should always produce fixed types in the result;
2010-05-04, by wenzelm
UNDISCH/DISJ_CASESL: eliminated slightly odd Thm.legacy_freezeT -- these rules appear to be applied to thms with fixed types only;
2010-05-03, by wenzelm
replaced Thm.legacy_freezeT by Thm.unvarify_global -- these facts stem from closed definitions, i.e. there are no term Vars;
2010-05-03, by wenzelm
renamed Thm.freezeT to Thm.legacy_freezeT -- it is based on Type.legacy_freeze;
2010-05-03, by wenzelm
minor tuning of Thm.strip_shyps -- no longer pervasive;
2010-05-03, by wenzelm
simplified primitive Thm.future: more direct theory check, do not hardwire strip_shyps here;
2010-05-03, by wenzelm
old NEWS on global operations;
2010-05-03, by wenzelm
ProofContext.init_global;
2010-05-03, by wenzelm
renamed ProofContext.init to ProofContext.init_global to emphasize that this is not the real thing;
