Description
Overload resolution (injections are inserted separately) Follows Sect. III:3.3 of the CASL Reference Manual. The algorthim is from: Till Mossakowski, Kolyang, Bernd Krieg-Brueckner: Static semantic analysis and theorem proving for CASL. 12th Workshop on Algebraic Development Techniques, Tarquinia 1997, LNCS 1376, p. 333-348

minExpFORMULAeq :: (FormExtension f, TermExtension f) => Min f e -> Sign f e -> (TERM f -> TERM f -> Range -> FORMULA f) -> TERM f -> TERM f -> Range -> Result (FORMULA f)
minExpTerm :: (FormExtension f, TermExtension f) => Min f e -> Sign f e -> TERM f -> Result [[TERM f]]
isUnambiguous :: Pretty f => String -> GlobalAnnos -> f -> [[f]] -> Range -> Result f
check if there is a unique equivalence class
oneExpTerm :: (FormExtension f, TermExtension f) => Min f e -> Sign f e -> TERM f -> Result (TERM f)
test if a term can be uniquely resolved
minimalSupers :: Sign f e -> SORT -> SORT -> [SORT]
minimal common supersorts of the two input sorts
maximalSubs :: Sign f e -> SORT -> SORT -> [SORT]
maximal common subsorts of the two input sorts
haveCommonSupersorts :: Bool -> Sign f e -> SORT -> SORT -> Bool
True if both sorts have a common supersort
haveCommonSubsorts :: Sign f e -> SORT -> SORT -> Bool
keepMinimals1 :: Bool -> Sign f e -> (a -> SORT) -> [a] -> [a]
keepMinimals :: Sign f e -> (a -> SORT) -> [a] -> [a]
only keep elements with minimal (and different) sorts
