UNDISCH/DISJ_CASESL: eliminated slightly odd Thm.legacy_freezeT -- these rules appear to be applied to thms with fixed types only;
wenzelm [Mon, 03 May 2010 20:53:49 +0200] rev 36616
replaced Thm.legacy_freezeT by Thm.unvarify_global -- these facts stem from closed definitions, i.e. there are no term Vars;
wenzelm [Mon, 03 May 2010 20:13:36 +0200] rev 36615
renamed Thm.freezeT to Thm.legacy_freezeT -- it is based on Type.legacy_freeze;
