Identity function.

the identity morphism
the identity morphism
Identity function.
id x = x
Identity bijection.
The identity function. This is useful when tying the knot, to avoid a loop that bottoms out:
let x = x in RB.get x
will not work, but
>>> let x = RB.id x in RB.get x
False
does.
RB.get (RB.id r) === RB.get r
