Library changes:

* `IO` operations in the `prelude` and `base` libraries now use the
|

`HasIO` interface, rather than using `IO` directly.
|

* Experimental `Data.Linear.Array` added to `contrib`, support mutable linear

arrays with constant time read/write, convertible to immutable arrays with

constant time read.

Internally, ``PrimIO Int`` is a function which takes the current (linear)

Interfaces and IO
|
||||
=================
|
||||
|
||||
In general, ``IO`` operations in the libraries aren't written using ``IO``
|
||||
directly, but rather via the ``HasIO`` interface:
|
||||
|
||||
.. code-block:: idris
|
||||
|
||||
interface Monad io => HasIO io where
|
||||
liftIO : (1 _ : IO a) -> io a
|
||||
|
||||
``HasIO`` explains, via ``liftIO``, how to convert a primitive ``IO`` operation
|
||||
to an operation in some underlying type, as long as that type has a ``Monad``
|
||||
implementation. These interface allows a programmer to define some more
|
||||
expressive notion of interactive program, while still giving direct access to
|
||||
``IO`` primitives.
