One situation -- where this can be useful is when writing a function to extract a value from -- a data structure. Suppose you write an implementation of arrays and offer -- only this function to index into them: -- -- @ -- index :: Array a -> Int -> a -- @ -- -- Now imagine that someone wants to extract a value from an array and store it -- in a lazy-valued finite map/dictionary: -- -- @ -- insert "hello" (arr `index` 12) m -- @ -- -- This can actually lead to a space leak. The value is not actually extracted -- from the array until that value (now buried in a map) is forced. That means -- the entire array may be kept live by just that value! Often, the solution -- is to use a strict map, or to force the value before storing it, but for -- some purposes that's undesirable. -- -- One common solution is to include an indexing function that can produce its -- result in an arbitrary @Applicative@ context: -- -- @ -- indexA :: Applicative f => Array a -> Int -> f a -- @ -- -- When using @indexA@ in a /pure/ context, @Solo@ serves as a handy -- @Applicative@ functor to hold the result.
