What's included?

Importing Runes introduces 3 new operators and one global function:

  • <^> (pronounced "map")
  • <*> (pronounced "apply")
  • >>- (pronounced "flatMap")
  • pure (pronounced "pure")

We also include default implementations for Optional and Array with the following type signatures:

// Optional:
public func <^><T, U>(f: T -> U, a: T?) -> U?
public func <*><T, U>(f: (T -> U)?, a: T?) -> U?
public func >>-<T, U>(a: T?, f: T -> U?) -> U?
public func pure<T>(a: T) -> T?

// Array:
public func <^><T, U>(f: T -> U, a: [T]) -> [U]
public func <*><T, U>(fs: [T -> U], a: [T]) -> [U]
public func >>-<T, U>(a: [T], f: T -> [U]) -> [U]
public func pure<T>(a: T) -> [T]
