This introduce a code base way of modifying the ast. This allow to use Template strings with the two special variable names names `__code__` and `__ret__` allowing to quickly write a magic, or hooks that modify the ast. This also introduce a `%code_wrap` cell magic to on the fly wrap code. It is this easy to for example modify IPython to say time each block of code, or retry them, or wrap them in try/except and analyse the error message, profile... Note that this is not new, but simply convenience function and utilities, especially around hygiene.
