Nice but Oi! it is complicated!
There may be an easier solution.
What I want to do is use the variable within the module itself and export them for the
user to use if they want.
What I don't want is the user to import a function that uses the variable internally
and the variable, change it to something evil, and then call the function.
Could I use a my variable intrenall and export the and our variable with the sam data
then use the my variable internally and export the our version? IE
my $foo = 02173;
our $_foo = $foo;
Then they can export and change $_foo all they want but they can't change the my $foo
so I can use it safley internally.
Using my() in a module won't be a problem right just trying to export a my() variable
is bad and evil, correct?
