Argparse's source is possibly the most difficult lib to grow from the stdlib. https://github.com/python/cpython/blob/master/Lib/argparse.p...

For me, it is not debugable. I wanted to propose and start a reference implementation for supporting --[no-]bool-opt, but I quickly gave up. There's some solutions on SO, but none of them are sufficient. The best solution makes --bool-opt mutually exclusive to --no-bool-opt which will cause a hard failure which is not okay for shell aliases.
