I strongly advise against this.  All of the things a script does should
be discoverable by reading the script, and any files that are explicitly
dotted in (sourced) by that script.

There shouldn't be any surprises coming in from the execution environment.

If your script needs external variables, it should explicitly dot in a
file that sets just those variables.  (Usually, /etc/default/ or ~/.config/
contains files of this type.)  Such a file should NOT be a user's .bashrc
because that can change on a whim, and may do things that the script
would neither expect nor desire.
