1# The inspect.formatargspec() function was dropped in Python 3.11 but we need 

2# need it for when constructing signature changing decorators based on result of 

3# inspect.getargspec() or inspect.getfullargspec(). The code here implements 

4# inspect.formatargspec() base on Parameter and Signature from inspect module, 

5# which were added in Python 3.6. Thanks to Cyril Jouve for the implementation.
