Docstrings for #[new] method implementations

[djc]

When I write a docstring on a #[new] fn new() method in a #[pymethods] impl block, I would expect this to show up in the help() output for the type. Instead, the help() output seems to end up with a default docstring:

 |  Static methods defined here:
 |
 |  __new__(*args, **kwargs)
 |      Create and return a new object.  See help(type) for accurate signature.

Is there no way in Python's data model to enable a specific help string for this? The docstring for the type ends up making it into the output sort of next to the constructor type signature, so I guess I could use that. Just seems surprising.

Sorry for the slow reply. I think this is just an oversight that we should be able to improve, I opened #4326 to track this.

Thanks!
