Since message is passed in super.__init__(message) and we removed the custom __str__ implementation below, this is already the default implementation.
In Python, __str__ isn't helpful. If you need to know the class name, then __repr__ is required, and our __repr__ implementation contains all information about the current exception, including errors.
>>> e = ValueError("abandon ship!")
>>> str(e)
'abandon ship!'
>>> repr(e)
"ValueError('abandon ship!')"| def __str__(self) -> str: | ||
| if self.errors: | ||
| return f"Connection error caused by: {self.errors[0].__class__.__name__}({self.errors[0]})" | ||
| return "Connection error" | ||

This __str__ implementation tries to be helpful but hides the current exception to focus on errors, which are past attempts. This comment applies to the other subclasses as well.

This is all the information exposed by __repr__, but in a more structured way which is nicer to test for.

Closes #223
While this does not change any types, it does change the values returned by
str(e)andrepr(e), so I would like to include this in 9.0 only, without backporting to 8.x.
