Also, for something like this:
In [1]: class A:
...: pass
...:
In [2]: A(x=2)
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-2-857108bff989> in <module>()
----> 1 A(x=2)
TypeError: object() takes no parameters
It would be nice to say TypeError: object() takes no parameters, but
keyword argument "x" given. I understand that the value of "x" might not
have a __repr__ method, but the key name has to be string, so this should
be easily doable at least for extra keyword arguments? For positional
arguments, maybe just print how many were passed to object? Knowing the
key name would have helped me with debugging. Usually, I print(kwargs)
somewhere up the inheritance chain and run my program again.
