Indeed, the error message does not help to identify the problem. Moreover, it collides with similar errors in namedtuple and DynamicClassAttribute which may lead to even more confusion.

I made a draft patch that could help with it (https://github.com/Alex-Blade/cpython/commit/06df3a72dfe462c8fe4eac60dce0ef059b1738f8), but I have a concern related to backwards compatibility (that's why no PR). I don't really understand if according to PEP 387 a change in an exception message should be considered compatibility breaking?
