cabal-install-solver Distribution.Solver.Compat.Prelude A Map from keys k to values a. The Semigroup operation for Map is union, which prefers values from the left operand. If m1 maps a key k to a value a1, and m2 maps the same key to a different value a2, then their union m1 <> m2 maps k to a1.

core-data Core.Data.Structures A mapping from keys to values. The keys in a map needs to be an instance of the Key typeclass. Instances are already provided for many common element types. Map implements Foldable, Monoid, etc so many common operations such as foldr to reduce the structure with a right fold, length to get the number of key/value pairs in the dictionary, null to test whether the map is empty, and (<>) to join two maps together are available. To convert to other dictionary types see fromMap below. (this is a thin wrapper around unordered-containers's HashMap, but if you use the conversion functions to extract the key/value pairs in a list the list will be ordered according to the keys' Ord instance)
