Oh, right. Looking back, turns out Wing IDE did that for me. Didn't notice, sorry.

I understand your perspective.

One correction though regarding adding noise to the error. You gave this example:

    builtins.TypeError: package.some_module.MyClass.__init__ takes 1 positional argument but 2 were given
    
While actually it'll be:

    TypeError: MyClass.__init__ takes 1 positional argument but 2 were given
    
Since __qualname__ only includes the class, not its module. So it's quite a bit shorter.
