14 * Eliminate Thy_Info.get_theory eventually: should take theory from ancestory
15 within current context.
17 * Clarify symmetric rule: Thm.apply_attribute Calculation.symmetric thm context (!?);
19 * KEStore_Elems: Should we eliminate union_overwrite and use standard namespace merge?
20 (Exception: rlss with its special cross-theory merge.)
22 * What is the purpose of "#numeral" instead of plain numeral?
24 * Check/clarify Context.theory_name vs. Context.theory_long_name.
26 * Eliminate mutable Rewrite_Ord.rew_ord' (!?);
28 * What is the idea behind KEStore_Elems.add_thes? How to do it properly in current Isabelle?
31 * WN: clarify add_calcs with non-existant constant "Integrate.add_new_c";
33 * WN: proper ML antiquotations for "Tactical.Try" etc. --- be careful about unclear situations,
34 e.g. "Tactical.Try" vs. "Lucas_Interpreter.Try";
36 * WN: eliminate ThmC.numerals_to_Free, use existing Isabelle/HOL representation
37 - clarify role of type "real" vs. "float" (see theory "HOL-Library.Float");
39 * WN: proper formal context with theory HOL-Library.Float, proper antiquotation @{const_name Float};
40 (e.g. theory ISAC_Base imports "HOL-Library.Floar" instead of HOL.Complex_Main);
42 * WN: clarify Rule.Thm ("minus_divide_left", ...): Should this be @{rule_thm_sym} antiquotation?
44 * WN: check remaining MethodC.prep_input that use a different theory (e.g. "Diff"):
45 Is this really required, or can we just use the 'method' command?
47 * WN: trim-down MethodC.prep_input and Problem.prep_input to what is really needed;
48 improve errors via parse_term_strict;
50 * WN: eliminate global flags like "trace_on", replace Unsynchronized.ref by
52 ML \<open>val rewrite_trace = Attrib.setup_config_bool \<^binding>\<open>rewrite_trace\<close> (K false);\<close>
54 * WN: Avoid Thm.get_name_hint --- somewhat fragile.
56 * WN: eliminate ThyC.to_ctxt, use Proof_Context.init_global inline to make more
57 clear where the normal Isabelle context-discipline is bypassed;
59 * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
60 - quite often "axiomatization ..." can be turned into "lemma ... by auto"
62 - sometimes this requires to use more specific types / type classes;
63 - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
64 - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
66 * WN: eliminate ThmC.numerals_to_Free, use existing Isabelle/HOL representation, DONE partially;
67 + TOODOO are exclusive for this changeset; most follow from TOODOO.1
68 + TOODOO.1: exception TYPE raised by Skip_Proof.make_thm
69 + ? how to do algebraic operations on numerals ? Presburger ? simplifier ?
70 + clarify role of type "real" vs. "float" (see theory "HOL-Library.Float");
72 * WN: DONE cleanup remaining ^^^ in comments (but sometimes it is just ASCII art), partially;
73 Left ^^^ in doc-isac (old master-theses, etc: "x^^^#2 + #8" ... # are left, too)
74 Left "ASCII art" in case of indicating comments pointing at facts ABOVE.
76 * WN: "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
79 * WN: reduce the number of TermC.parse*;
80 - one or two variants should suffice.
