New submission from Nicholas Matthews <nmatth...@asapp.com>:
The class inspect.Signature asks for parameters of type dict in python 3.8+
(and OrderedDict in earlier versions); however the __init__ function iterates
over parameters as if it were a list, specifically:
for param in parameters:
name = param.name
kind = param.kind
...
Either the docstring should be changed to specify Sequence / List, or the
implementation should be changed to iterate over the values of parameters:
for param in parameters.values():
...
