Apologies for not being clear.
So I wrote:

In IPython (or Jupyter), `inspect.getsource` is able to retrieve the source code for functions but not classes.

By this I mean:

import inspect

class X:
  pass

inspect.getsource(X)

Note that:
- it won't work in the vanilla python interpreter,
- it does work for functions in Jupyter/IPython currently,
- it works for classes (and functions) in modules.
What I would like is to have it work for classes in Jupyter/IPython.

By the way: Would a PR be more convenient than a patch?
