14 * Eliminate Thy_Info.get_theory eventually: should take theory from ancestory
15 within current context.
16 cf. e587c45cae0f note in Build_Thydata.thy
18 * Clarify symmetric rule: Thm.apply_attribute Calculation.symmetric thm context (!?);
20 * KEStore_Elems: Should we eliminate union_overwrite and use standard namespace merge?
21 (Exception: rlss with its special cross-theory merge.)
23 * What is the purpose of "#numeral" instead of plain numeral?
25 * Check/clarify Context.theory_name vs. Context.theory_long_name.
27 * Eliminate mutable Rewrite_Ord.rew_ord' (!?);
28 shall be done in connection with cf. e587c45cae0f note in Build_Thydata.thy
30 * What is the idea behind KEStore_Elems.add_thes? How to do it properly in current Isabelle?
31 cf. e587c45cae0f note in Build_Thydata.thy
33 * WN: clarify add_calcs with non-existant constant "Integrate.add_new_c";
35 * WN: proper ML antiquotations for "Tactical.Try" etc. --- be careful about unclear situations,
36 e.g. "Tactical.Try" vs. "Lucas_Interpreter.Try";
38 * WN: eliminate global flags like "trace_on", replace Unsynchronized.ref by
39 ML \<open>val rewrite_trace = Attrib.setup_config_bool \<^binding>\<open>rewrite_trace\<close> (K false);\<close>
41 * WN: Avoid Thm.get_name_hint --- somewhat fragile.
43 * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
44 - quite often "axiomatization ..." can be turned into "lemma ... by auto"
46 - sometimes this requires to use more specific types / type classes;
47 - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
48 - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
50 * WN: eliminate ThmC.numerals_to_Free, done except 1 error:
51 + exception TYPE raised by Skip_Proof.make_thm, several inherited errors in tests marked TOODOO.1
52 + ? how do algebraic operations on numerals ? Presburger ? simplifier ? hack see

55 * WN: DONE cleanup remaining ^^^ in comments (but sometimes it is just ASCII art), partially;
56 Left ^^^ in doc-isac (old master-theses, etc: "x^^^#2 + #8" ... # are left, too)
57 Left "ASCII art" in case of indicating comments pointing at facts ABOVE.
59 * WN: "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
62 * WN: reduce the number of TermC.parse*;
63 + 0d22a6bf1fc6 was too much for 1 changeset
64 + first parse with ctxt in Specify (O_Model.init shall return a context,..) etc
66 * WN: push suggestions of MW through the whole code
67 + e1da148725ed : \<^ML>\<open>...\<close> instead of parentheses
