A script with no commands should be valid in any language, in my
opinion.  As a matter of principle, but also for practical reasons:
You may want to comment by chance all code.  I think this way the
matter appeared to me.  You may also want to write a template with all
code commented initially.

I don't think that was my issue.

Frightening prospect...
