I've noticed that using argparse makes my scripts start very slow, especially if you expose a large number of option. I have a script that I wrote for work that has quite a variable number of available options and it can sometimes take several seconds for the script to startup and actually begin doing anything useful.

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.
