val ident : α → α
 ## The identity function, (ident x ≡ x), also known as the I combinator.

val konst : α → β → α
 ## (konst x y ≡ x).  (konst) is also known as the K combinator.

val 2'∘ : (β → γ) → (α → β) → α → γ
 ## Function composition, ((f ∘ g) x ≡ f (g x)).

val 2'*> : (α → β) → (β → γ) → α → γ
 ## Function composition with arguments reversed.

val 2'<| : (α → β) → α → β
 ## (f <| x ≡ f x) is the value of (f) at (x).  I.e. (<|) is a low-precedence
 ## variant of the application operator.  It can be pronounced "at" or "of".

val 2'|> : α → (α → β) → β
 ## (x |> f ≡ f x) is the image of (x) under (f).  I.e. (|>) is a reversed
 ## low-precedence application operator.  It can be pronounced "under".

# This is the analog of prelude.ubiquitous for client code.
