Ideally you wouldn't do it that way.  If you have modules that need
values from the calling script, you should either pass them to the subs
you call, create a module with subs that you can use to access them, or
export them from a module which the different parts of your script can
share.  The last is closest to what you're doing now.  Take a look at
the examples of sharing config data here:
