Description
Description
That gets unrolled at some stage of the compilation pipeline.
This allows us and users to easily rewrite gradient graphs before they get "messy". This covers a lot of the discussion in #182

Research direction
Start by tracing grad through the compilation pipeline and identify where gradient graphs are currently unrolled. The work is done when grad can remain a dummy Op long enough for PyTensor and users to rewrite gradient graphs before unrolling.
