Since this is my first code in D, I apologize in advance for the
mix if Python and C++ idioms. Since this is ported from Python,
with the intention of staying compatible with future Python
versions, some of that is expected, but I look for this as an
chance to learn more about D.

It is also a pretty useful way to write commandline interfaces.
The included example that mimics the git CLI is pretty impressive.

This is also my first submission as a dub project, so hopefully I
got that right as well.

Still needs more tests ported from Python, but it does pass the
entire functional test suite for the current Python version.

Pretty cool idea. Are you aware of that in D you can, at compile time, parse the doc string and generate a command line parser for that particular documentation.

Looking at the git example [1], it seems a bit complicated and verbose to use after parsing. To determine which arguments was passed to the application.
