toList :: Foldable t => t a -> [a]ghc-internal GHC.Internal.Data.Foldable List of elements of a structure, from left to right. If the entire list is intended to be reduced via a fold, just fold the structure directly bypassing the list.
Examples
Basic usage:>>> toList Nothing []
>>> toList (Just 42) [42]
>>> toList (Left "foo") []
>>> toList (Node (Leaf 5) 17 (Node Empty 12 (Leaf 8))) [5,17,12,8]
For lists, toList is the identity:>>> toList [1, 2, 3] [1,2,3]

ghc-internal GHC.Internal.Data.Maybe The maybeToList function returns an empty list when given Nothing or a singleton list when given Just.
Examples
Basic usage:>>> maybeToList (Just 7) [7]
>>> maybeToList Nothing []
One can use maybeToList to avoid pattern matching when combined with a function that (safely) works on lists:>>> import GHC.Internal.Text.Read ( readMaybe ) >>> sum $ maybeToList (readMaybe "3") 3 >>> sum $ maybeToList (readMaybe "") 0
