Could we fail on unknown Attribute?

Could we please add another config option in addition to fail_on_unknown_properties to fail on unknown Attribute?

I don’t currently see that functionality and I’ve experimented by adding random attributes to my parser and they didn’t crash or raise a TypeError.

I am using attrs plugin with the kw_only flag set to true in the config.

I would be expecting similar behaviour to this:

In [1]: import attr

In [2]: @attr.s(frozen=True, slots=True, kw_only=True)
   ...: class Test:
   ...:     a: int = attr.ib()
   ...:     b: str = attr.ib()

In [3]: Test(**{'a': 3, 'b': 'test', 'c': 'tent'})
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-10-715d11a185fb> in <module>
----> 1 Test(**{'a': 3, 'b': 'test', 'c': 'tent'})

TypeError: __init__() got an unexpected keyword argument 'c'
