Currently the repr of re flags contains the name of the private class and it is not an evaluable expression:
The repr of inverted flags is even more verbose:
The result of str() starves from the same issues.
If the value contains unrecognized flags, it looks even more weird, and this information is not shown for invered flags:
This repr is also not consistent with the represenation of flags in the repr of the compiled pattern:
The proposed PR makes the repr be the same as for flags in the repr of the compiled pattern and represents inverted flags as the result of inversion:
__str__ is set to object.__str__, so that str() will return the same as repr().
