2011-05-19 blanchet 2011-05-19 renamed "simple_types" to "simple"
2011-05-19 blanchet 2011-05-19 since we always default on the "_light" encoding (for good reasons, according to Judgment Day), get rid of that suffix
2011-05-19 blanchet 2011-05-19 honor "conj_sym_kind" also for tag symbol declarations
2011-05-19 blanchet 2011-05-19 removed "poly_tags_light_bang" since highly unsound

2011-05-13 blanchet 2011-05-13 avoid "UnequalLengths" exception for special constant "fequal" -- and optimize code in the common case where no type arguments are needed
2011-05-13 blanchet 2011-05-13 make SML/NJ happy
2011-05-12 blanchet 2011-05-12 fixed several bugs in Isar proof reconstruction, in particular w.r.t. mangled types and hAPP
2011-05-12 blanchet 2011-05-12 robustly detect how many type args were passed to the ATP, even if some of them were omitted
2011-05-12 blanchet 2011-05-12 make sure "simple_types_query" and "simple_types_bang" symbols are declared with the proper types
2011-05-12 blanchet 2011-05-12 drop some type arguments to constants in unsound type systems + remove a few type systems that make no sense from the circulation
2011-05-12 blanchet 2011-05-12 ensure Set.member isn't introduced by Meson's preprocessing if it's supposed to be unfolded
2011-05-12 blanchet 2011-05-12 use the same code for extensionalization in Metis and Sledgehammer and generalize that code so that it gracefully handles negations (e.g. negated conjecture), formulas of the form (%x. t) = u, etc.
2011-05-12 blanchet 2011-05-12 unfold set constants in Sledgehammer/ATP as well if Metis does it too
2011-05-12 blanchet 2011-05-12 don't give weights to built-in symbols
2011-05-12 blanchet 2011-05-12 gracefully declare fTrue and fFalse proxies' types if the constants only appear in the helpers
2011-05-12 blanchet 2011-05-12 improve detection of quantifications over dangerous types by leveraging "is_type_surely_finite" predicate and added "prop" to the list of surely finite types
2011-05-12 blanchet 2011-05-12 ensure type class predicates are generated in symbol declarations (for "poly_preds" and similar)
2011-05-12 blanchet 2011-05-12 avoid "Empty" exception by making sure that a certain optimization only is attempted when it makes sense

2011-05-06 blanchet 2011-05-06 allow each prover to specify its own formula kind for symbols occurring in the conjecture

2011-05-05 blanchet 2011-05-05 added FIXME
2011-05-05 blanchet 2011-05-05 help SOS by ensuring that typing information is marked as part of the conjecture + be more precise w.r.t. typedefs in monotonicity check
2011-05-05 blanchet 2011-05-05 query typedefs as well for monotonicity
2011-05-05 blanchet 2011-05-05 hopefully this will help the SML/NJ type inference
2011-05-05 blanchet 2011-05-05 reverted 6efda6167e5d because unsound -- Vampire found a counterexample
2011-05-05 blanchet 2011-05-05 I have an intuition that it's sound to omit the first type arg of an hAPP -- and this reduces the size of monomorphized problems quite a bit
2011-05-05 blanchet 2011-05-05 removed unsound hAPP optimization
2011-05-05 blanchet 2011-05-05 versions of ! and ? for the ASCII-challenged Mirabelle
