Definitions

interface LinearBind : (Type -> Type) -> Type

  Like `Monad`, but the action and continuation must be run exactly once
  to ensure that the computation is linear.

Parameters: io
Methods:

bindL : io a -@ ((a -> io b) -@ io b)

Implementation: 

LinearBind IO

bindL : LinearBind io => io a -@ ((a -> io b) -@ io b)

Visibility: public export

data Usage : Type

  Required usage on the result value of a computation

data L : (Type -> Type) -> {default Unrestricted _ : Usage} -> Type -> Type

  A wrapper which allows operations to state the multiplicity of the value
  they return. For example, `L IO {use=1} File` is an IO operation which
  returns a file that must be used exactly once.

  underlying context

bang : L IO t -@ L1 IO ((!*) t)

  Shuffling around linearity annotations: a computation of an
  unrestricted value can be seen as a computation of a linear
  value that happens to be unrestricted.
