fn

fn creates an anonymous function.

Syntax

(fn (⟨arg⟩ ...) ⟨body⟩)

Semantics

• fn is the standard way to write lambdas in Coalton.
• A closure is allocated when variables are captured.
• fn also supports keyword arguments with &key.
• return may be used to return a value from the function.

Example

(fn (x)
  (+ x 2))
