Well, yes, but personally I'd prefer to just run with "#!/usr/bin/env 
python3". Then the command line will say "python3: not found" or 
similar, I can fix my environment, and thereafter everything works 
better. Rather than complex magic inside a script.

If we're going to accept the approach though, I'd rather the shebang was 
just "#!/bin/sh". There's _always_ a /bin/sh, and a number of BSDish 
systems do not have a /usr/bin/env (it tends to land in /bin instead).
