Using "our" should work, provided you reference the variables with their
full names:
$Some::Variable::In::Another::Package = "foo";
But "man perlfunc" says the following in the "our" entry:
An "our" declaration declares a global variable that will be
visible across its entire lexical scope, even across package
boundaries. The package in which the variable is entered is
determined at the point of the declaration, not at the point of
use. This means the following behavior holds:
package Foo;
our $bar; # declares $Foo::bar for rest of lexical scope
$bar = 20;
package Bar;
print $bar; # prints 20
This is in perl5/5.6.1/pod/perlfunc.pod, but "our" seems to have evolved
recently (while I wasn't watching), so maybe it doesn't work this way in
older versions?
In any case, the important point is that "our" variables are scoped
to the file (strictly, the rest of the file after the point of
declaration). Does that maybe explain why "our" didn't seem to work?
