in reply to Export global variables not working correctly

I afraid the best you can do is use Alias. However for object instances you'll have to use a reference to the other object, you should think in these terms and not try to use Packages as Namespaces.

    What's this about not trying to use packages as namespaces? The last time I looked at perlmod, I read this:

    Perl provides a mechanism for alternative namespaces to protect packages from stomping on each other's variables. In fact, there's really no such thing as a global variable in Perl. The package statement declares the compilation unit as being in the given namespace.

    And perlobj says:

    A package is simply a namespace containing variables and subroutines.

      This thinking only works if you can stop any one from using bless and your package. Afterwards your namespace is no longer just a namespace.

        I've tried to wrap my head around what you are saying and am not getting anything. Would you mind showing a quick code example of the situation you are talking about?
