In master calling inspect.getfullargspec on some function now returns only args/kwargs. I suspect that this is due to the recent __array_function__ wrapping, though I am not sure.

Reproducing code example:

import numpy as np       
import inspect       
print(inspect.getfullargspec(np.nansum))
FullArgSpec(args=[], varargs='args', varkw='kwargs', defaults=None, kwonlyargs=[], kwonlydefaults=None, annotations={})  # version 1.16.0.dev0+db5750f
FullArgSpec(args=['a', 'axis', 'dtype', 'out', 'keepdims'], varargs=None, varkw=None, defaults=(None, None, None, <no value>), kwonlyargs=[], kwonlydefaults=None, annotations={})  # version 1.15.1

The inspect.signature function seems to work fine.

Yes, see dask/dask#4111 and #12225

Closing this in favor of #12225.
