Stretched values

data Stretched a

A Stretched value has a known duration, but no position.

Placing a value inside Stretched makes it invariant under delay, however the inner value can still be delayed using fmap delay.

Construction

stretched :: Iso (Duration, a) (Duration, b) (Stretched a) (Stretched b)

View a stretched value as a pair of the original value and a stretch factor.

stretchedValue :: (Transformable a, Transformable b) => Lens (Stretched a) (Stretched b) a b

View a stretched value as a pair of the original value and the transformation (and vice versa).
