sequenceA :: (Traversable t, Applicative f) => t (f a) -> f (t a)relude Relude.Foldable.Reexport Evaluate each action in the structure from left to right, and collect the results. For a version that ignores the results see sequenceA_.
Examples
Basic usage: For the first two examples we show sequenceA fully evaluating a a structure and collecting the results.>>> sequenceA [Just 1, Just 2, Just 3] Just [1,2,3]
>>> sequenceA [Right 1, Right 2, Right 3] Right [1,2,3]
The next two example show Nothing and Just will short circuit the resulting structure if present in the input. For more context, check the Traversable instances for Either and Maybe.>>> sequenceA [Just 1, Just 2, Just 3, Nothing] Nothing
>>> sequenceA [Right 1, Right 2, Right 3, Left 4] Left 4
sequenceA_ :: (Foldable t, Applicative f) => t (f a) -> f ()relude Relude.Foldable.Reexport Evaluate each action in the structure from left to right, and ignore the results. For a version that doesn't ignore the results see sequenceA. sequenceA_ is just like sequence_, but generalised to Applicative actions.
Examples
Basic usage:>>> sequenceA_ [print "Hello", print "world", print "!"] "Hello" "world" "!"
sequence_ :: (Foldable t, Monad m) => t (m a) -> m ()relude Relude.Foldable.Reexport Evaluate each monadic action in the structure from left to right, and ignore the results. For a version that doesn't ignore the results see sequence. sequence_ is just like sequenceA_, but specialised to monadic actions.

relude Relude.List.Reexport The subsequences function returns the list of all subsequences of the argument.
Laziness
subsequences does not look ahead unless it must:>>> take 1 (subsequences undefined) [[]] >>> take 2 (subsequences ('a' : undefined)) ["","a"]Examples
>>> subsequences "abc" ["","a","b","ab","c","ac","bc","abc"]
This function is productive on infinite inputs:>>> take 8 $ subsequences ['a'..] ["","a","b","ab","c","ac","bc","abc"]
