wenzelm@60316: * Eliminate Thy_Info.get_theory eventually: should take theory from ancestory
walther@60363:   within current context.
walther@60362:     cf. e587c45cae0f note in Build_Thydata.thy
wenzelm@60316: 
wenzelm@60295: * Clarify symmetric rule: Thm.apply_attribute Calculation.symmetric thm context (!?);
walther@60369:     ??
wenzelm@60295: 
wenzelm@60316: * KEStore_Elems: Should we eliminate union_overwrite and use standard namespace merge?
wenzelm@60316:   (Exception: rlss with its special cross-theory merge.)
wenzelm@60285: 
wenzelm@60281: * What is the purpose of "#numeral" instead of plain numeral?
walther@60368:     ??
wenzelm@60281: 
wenzelm@60281: * Check/clarify Context.theory_name vs. Context.theory_long_name.
walther@60369:     present ISAC assumes 2 sessions in the MathEngine, Specify and Interpret, 
walther@60369:     and all Isac_Knowledge is in session Isac.
walther@60369:     So Context.theory_name suffices
wenzelm@60281: 
wenzelm@60292: * Eliminate mutable Rewrite_Ord.rew_ord' (!?);
walther@60362:     shall be done in connection with cf. e587c45cae0f note in Build_Thydata.thy
wenzelm@60292: 
wenzelm@60315: * What is the idea behind KEStore_Elems.add_thes? How to do it properly in current Isabelle?
walther@60365:     https://static.miraheze.org/isacwiki/0/04/Isac-docu.pdf distinguishes 
walther@60365:     several kinds of ISAC users, in particular "math author (Mathematik-Autor)" and
walther@60365:     "course designer (Kurs-Designer)". The latter just adds examples which re-use existing
walther@60365:     knowledge designed by the former. KEStore_Elems.add_thes is an interface for the latter.   
wenzelm@60315: 
wenzelm@60311: * WN: proper ML antiquotations for "Tactical.Try" etc. --- be careful about unclear situations,
wenzelm@60311:   e.g. "Tactical.Try" vs. "Lucas_Interpreter.Try";
wenzelm@60311: 
walther@60371: * WN: Avoid Thm.get_name_hintand use Global_Theory.get_thm instead, get theory from References.T
walther@60370:     and push theory through as argument of respective functions.
wenzelm@60304: 
wenzelm@60241: * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
wenzelm@60241:     - quite often "axiomatization ..." can be turned into "lemma ... by auto"
wenzelm@60241:       without further ado;
wenzelm@60241:     - sometimes this requires to use more specific types / type classes;
wenzelm@60241:     - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
wenzelm@60241:     - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
wenzelm@60234: 
walther@60357: * WN: eliminate ThmC.numerals_to_Free, done except 1 error:
walther@60357:   + exception TYPE raised by Skip_Proof.make_thm, several inherited errors in tests marked TOODOO.1
walther@60357:   + ? how do algebraic operations on numerals ? Presburger ? simplifier ? hack see

walther@60245: 
wenzelm@60247: * WN: "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
walther@60317:       ???
walther@60317: 
walther@60317: * WN: reduce the number of TermC.parse*;
walther@60340:   + 0d22a6bf1fc6 was too much for 1 changeset
walther@60340:   + first parse with ctxt in Specify (O_Model.init shall return a context,..) etc
walther@60359: 
walther@60360: * WN: push suggestions of MW through the whole code
walther@60360:   + e1da148725ed : \<^ML>\<open>...\<close> instead of parentheses
walther@60370:   +
