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.
Map over a generator's shrink tree.
Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see mapM_.
Map each element of a structure to a monadic action, evaluate these actions from left to right, and ignore the results. For a version that doesn't ignore the results see mapM. As of base 4.8.0.0, mapM_ is just traverse_, specialized to Monad.
An associative operation NOTE: This method is redundant and has the default implementation mappend = (<>) since base-4.11.0.0. Should it be implemented manually, since mappend is a synonym for (<>), it is expected that the two functions are defined the same way. In a future GHC release mappend will be removed from Monoid.
Map a config modification function over a property.
Map between TreeT computations.
Map a function over all the elements of a container and concatenate the resulting lists.
Using ApplicativeDo: 'fmap f as' can be understood as the do expression
do a <- as
pure (f a)
with an inferred Functor constraint.
Map each element of the structure to a monoid, and combine the results.
