1 * WN: eliminate "handle _ => ..." (essential for PIDE interaction):
2 - either use \<^try>CARTOUCHE / \<^can>CARTOUCHE antiquotation
3 - or more basic try/can combinators;
4 - or more direct ML of intention;
6 * WN: check remaining "for tests only" wrt. \<^isac_test>CARTOUCHE;
8 * WN: purge BridgeLibisabelle: eliminate unused code;
11 * reconsider use of Thy_Info.get_theory: only works with batch-build, not within PIDE session;
14 * MW: ML antiqutation @{rule_thm NAME} to produce (Rule.Thm ("NAME", ThmC.numerals_to_Free "NAME"));
16 * MW: more concise "setup KEStore_Elems.add_rlss" etc.;
18 * MW: eliminate low-level TextIO (not portable);
20 * MW: check uses of Unsynchronized.ref vs. Synchronized.var;
22 * MW: proper formal name space for rule set, model patterns, methods;
25 * MW: clarify/eliminate Isabelle/Scala add-ons (presently unused)

36 * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
37 - quite often "axiomatization ..." can be turned into "lemma ... by auto"
39 - sometimes this requires to use more specific types / type classes;
40 - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
41 - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
42 - abbreviation real_powr :: "real \<Rightarrow> real \<Rightarrow> real" (infixr "\<up>" 80)
43 where "x \<up> a \<equiv> x powr a"
45 * WN: eliminate ThmC.numerals_to_Free, use existing Isabelle/HOL representation
46 - clarify role of type "real" vs. "float" (see theory "HOL-Library.Float");
48 * WN: investigate errors further which popped up in rewriting when replacing ^^^ by \<up> in ac7426ab0491.
49 The errors occur with examples in test/../poly.sml, which do not work properly in isabisac20 either.
51 * WN: cleanup remaining ^^^ in comments (but sometimes it is just ASCII art);
53 * WN: simplify const names like "is'_expanded": no need to imitate the escape of mixfix syntax;
55 * WN: proper statement for rcancel_den ("not" is a free variable!?!!):
56 rcancel_den: "not(a=0) ==> a * (b / a) = b" and
58 * WN: "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
