updated TODO;
     1 * reconsider use of Thy_Info.get_theory: only works with batch-build, not within PIDE session;
     2   + consider in Build_Thydata:  Thy_Hierarchy.insert_errpatIDs
     3   + consider in Biegelinie.thy: KEStore_Elems.add_thes, 
     4 
     5 * MW: check uses of Unsynchronized.ref vs. Synchronized.var;
     6 
     7 * MW: clarify/eliminate Isabelle/Scala add-ons (presently unused)

    18 * Clarify symmetric rule: Thm.apply_attribute Calculation.symmetric thm context (!?);
    19 
    20 * Is it possible to eliminate union_overwrite, in favour of more standard data
    21   add/merge discipline?
    22 
    23 * What is the purpose of "#numeral" instead of plain numeral?
    24 
    25 * Check/clarify Context.theory_name vs. Context.theory_long_name.
    26 
    27 * Eliminate mutable Rewrite_Ord.rew_ord' (!?);
    28 
    29 
    30 * WN: eliminate ThmC.numerals_to_Free, use existing Isabelle/HOL representation
    31     - clarify role of type "real" vs. "float" (see theory "HOL-Library.Float");
    32 
    33 * WN: clarify Rule.Thm ("minus_divide_left", ...): Should this be @{rule_thm_sym} antiquotation?
    34 
    35 * WN: check remaining MethodC.prep_input that use a different theory (e.g. "Diff"):
    36   Is this really required, or can we just use the 'method' command?
    37 
    38 * WN: remove always empty arguments in MethodC.prep_input and Problem.prep_input
    39   (following the "TODO" comment);
    40 
    41 * WN: trim-down MethodC.prep_input and Problem.prep_input to what is really needed.
    42 
    43 * WN: eliminate global flags like "trace_on", replace Unsynchronized.ref by
    44 
    45     ML \<open>val rewrite_trace = Attrib.setup_config_bool \<^binding>\<open>rewrite_trace\<close> (K false);\<close>
    46 
    47 * WN: Avoid Thm.get_name_hint --- somewhat fragile.
    48 
    49 * WN: eliminate ThyC.to_ctxt, use Proof_Context.init_global inline to make more
    50   clear where the normal Isabelle context-discipline is bypassed;
    51 
    52 * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
    53     - quite often "axiomatization ..." can be turned into "lemma ... by auto"
    54       without further ado;
    55     - sometimes this requires to use more specific types / type classes;
    56     - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
    57     - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
    58 
    59 * WN: "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
