Actually... You can! To quote the "man page" ("help page"?)[1]:

Typing the path to a non-executable (or by using "start") will use the
set association. What I tried was using `subprocess`, which
does not do this - and I guess the underlying C calls (`CreateProcess`
iirc) show the same behaviour (but I haven't tested this yet). And it
gave the same error for .py files as it did for .txt files, which is
"not a valid Win32 application".

Sounds good, we could probably use `ast` to parse the source, and build
our own interpreter (QutePy? PyPy v2?)... Stop giving me stupid ideas :P
