Unix-like systems have this courtesy of the shebang, so as long as
there's some sort of Python installed, people don't need to know or
care that /usr/local/bin/mailmail is implemented in Python. Maybe the
solution is to push for Windows to always include a Python
interpreter, which would allow a tiny stub to go and call on that?
Obviously a full shebang concept would be a huge change to Windows,
but if a 4KB executable can go and locate the rest of Python, or open
up a web browser saying "Please install OS update KB123456", that
would do it for most end users.
