14 public declarations

• applyfn(A) -> B -> A -> B

  A function applied to a value, for the places where a function is a value

  fn
• applyToA -> fn(A) -> B -> B

  A value passed to a function, reading left to right.

  fn
• composefn(B) -> C -> fn(A) -> B -> A -> C

  One function after another: `compose(f, g, x)` is `f(g(x))`.

  fn
• constantA -> B -> A

  A function that ignores its argument and answers with a fixed value.

  fn
• fixpointInt -> fn(T) -> T -> T -> T

  A function applied to itself's result until it stops changing.

  fn
• flipfn(A, B) -> C -> B -> A -> C

  A function with its two arguments exchanged.

  fn
• identityT -> T

  The value itself. Useful wherever a transformation is required and none is

  fn
• onfn(B, B) -> C -> fn(A) -> B -> A -> A -> C

  Two values compared after the same transformation is applied to each.

  fn
• partialfn(A, B) -> C -> A -> B -> C

  A two-argument function with its first argument fixed.

  fn
• pipefn(A) -> B -> fn(B) -> C -> A -> C

  One function after another, reading left to right.

  fn
• pipe3fn(A) -> B -> fn(B) -> C -> fn(C) -> D -> A -> D

  Three functions in a row, reading left to right.

  fn
• timesInt -> fn(T) -> T -> T -> T

  A function applied a number of times. A count below one is the value itself.

  fn
• twicefn(T) -> T -> T -> T

  A function applied twice.

  fn
• untilInt -> fn(T) -> Bool -> fn(T) -> T -> T -> T

  A function applied until a condition holds.
