class_docstr: A class that models and constructs operations in a graph.
  
  A `Op` instance has several responsibilities:
  
  * construct `Apply` nodes via :meth:`Op.make_node` method,
  * perform the numeric calculation of the modeled operation via the
    :meth:`Op.perform` method,
  * and (optionally) build the gradient-calculating sub-graphs via the
    :meth:`Op.grad` method.
  
  To see how `Op`, `Type`, `Variable`, and `Apply` fit together see the
  page on :doc:`graph`.
  
  For more details regarding how these methods should behave: see the `Op
  Contract` in the sphinx docs (advanced tutorial on `Op` making).

docstr: Make any special modifications that the `Op` needs before doing :meth:`Op.make_thunk`.
  
  This can modify the node inplace and should return nothing.
  
  It can be called multiple time with different `impl` values.
  
  .. warning::
  
      It is the `Op`'s responsibility to not re-prepare the node when it
      isn't good to do so.
