I think this is a good idea, but I think this is probably a shell spec issue
because I don't want competing, incompatible implementations.  

A few other issues: I think there is a persistence issue (similar to shell
variables) so that the change could be installed and survive a reboot. I
also think there can be a simple shell command that manages extensions (so
that they can be installed by a script)

Subject: [edk2-devel] Shell feature?

I wanted to start a conversation on the mailing list prior to writing up a
BZ, to make sure I'm not missing anything, or in case there is a better way
to implement this. 

I was thinking it would be good to have a Shell API that lets you associate
a file type with an internal or external shell command. The Idea would be to
pre-pend the internal/external shell command to the file name and also pass
the arguments.

So this:
fs0:>dump.py 1  2 3

Becomes:
fs0:>python3.efi dump.py 1  2 3

Basically you just need an API like:

ShellAddScriptingLanguage (L".py", L"python3.efi");

Seems like this could just plug into the Shell via a ShellExecute(). So for
example you could make Python a UEFI Shell command via a library and that
library constructor could also teach the shell that a .py file could be an
executable?

Thanks,
