Since none of currently active core-devs have deep expertise inargparse, but we still need to fix bugs in this module. The best way to start is to add more tests and increase the coverage of this module.

Right now it has a pretty solid coverage of 97%

You can get this yourself:

# compile python, create and activate venv, then:./python.exe -m pip install coveragecoverage run --pylib --branch --source=argparse -mtest -v test_argparsecoverage html

Here's the initial (current) state report.argparse_coverage.tar.gz

Any help is welcome :)
