I'm aware that perl has locally global variables.
However I thought the poster referred to globals in VB, which as I recall if declared in a module can be package globals in all packages simultaneously. However my recall may be incorrect since I have seen the light of the holy Perl and left icky VB behind (in other words I haven't used it for a while). Any way this would mean that one instance of the global var $foo is accessible in all packages without using a fully qualified name. This can be useful for a very common function, status variable or a useful constant. However perl does not have global globals and that is the question I was answering.
