Re^2: Export global variables not working correctly

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.	[reply]

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?	[reply]
