In computer programming, a nested function (or nested procedure or subroutine) is a function which is defined within another function, the enclosing function. -- Problem! Foldr Foldl Foldl … You can write the same thing in Haskell: -- With list comprehension scale root mode = [mod (root + i) 12 | i <- mode] -- With lambda functions / map scale root = map (\i -> mod (root + i) 12) Function definition is where you actually define a function. There is one other kind of pattern allowed in Haskell. List comprehensions can also draw elements from multiple lists, in which case the result will be the list of every possible combination … Those which can use lambda, can achieve the same expressiveness, maybe, but I don't consider them languages with nested functions.
