Please see my 3rd attempt at explaining this "use" business.

One problem with importing all of the @EXPORT stuff by default is that this can cause name conflicts. Also, if a program is large and uses a lot of modules, having an explicit import list can help with figuring out later what module something is in.

Yes, if a variable is an "our" variable, the fully qualified name will work even if that particular symbol is not exported/imported. subs/functions go into the package symbol table in any event. One aspect of this is that there is no such thing as a truly private function in Perl. It is considered very bad form to call some function that is not part of the public interface, but Perl will not stop you from shooting yourself in the foot like that. If you know the function's name, you can call it.

Oh, another point, in the @EXPORT list, you can ditch the leading & character (that's an old Perl 4 artifact). Put "someFunction" instead of "&someFunction".
