True, it's well suited for such program, but maybe it isn't that bad
also for the shell?

I think yes: it would work similar to warn_create_global – when
working on a script it would emit such warnings and inform the
programmer of the problem. The programmer would then react and change
the code, preventing it to be released to the public, like in the case
of creating a global.

Thanks, that's an interesting idea.
