map f xs is the list obtained by applying f to each element of xs, i.e., 
map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
map f [x1, x2, ...] == [f x1, f x2, ...]

map :: (MonadGen m, Ord k) => Range Int -> m (k, v) -> m (Map k v)
hedgehog Hedgehog.Gen Hedgehog.Internal.Gen
Generates a map using a Range to determine the length. This may fail to generate anything if the keys produced by the generator do not account for a large enough number of unique items to satify the required map size.

data () => Map k a
integration Testlib.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.
