Re: guix environment shebang interpreter

Great!

however, note that at two different time points, you can get different 
versions of python with
this command as the executing machine might have different versions of 
guix.

Only if you pull a specific version of guix (e.g. with guix pull 
--commit) and have it in your PATH
you will get the same packages.

Best regards,
Moritz
