Part of #1519.

This was what I was talking about in #1519 (comment). __new__ and __call__ are part of the models for object and classes. Thus, instead of adding them as attr___ne__ I think it makes sense to try and define them.

One thing I wonder is whether this should indeed be properties. But looking at other methods I think they should? See for example:
https://github.com/PyCQA/astroid/blob/01db68b1b37fdfa4d7899fa1ba71015b33efb34b/astroid/interpreter/objectmodel.py#L288-L289

Thanks for pushing forward on this. I haven't found time to do a review yet, but I did quickly check it against pylint-dev/pylint#6402 and this doesn't pass its test case. Was that expected?

Yeah! Ultimately we should merge #1519 as well.

However, since __new__ and __init__ are used so ubiquitously I thought there would be benefits to defining them rather than making them attr___ne__. I think for the other dunders most tests will automatically pass if we define them on ObjectModel instead of FunctionModel. (Although I haven't checked).

Looks really good! One last Q
