Not to be nosy, but what do you need this for? It's likely that you should use a different approach than creating a package-spanning global. If you tell us what you need it for, maybe someone can suggest a better idea.

Comment on Re: How to make global variable, like %ENV
Is for the HWX enverioment. Since the HWX apps can be runed in many packages in the same time, I can't export %HWX to %foo::HWX, because when the app goes out I need to read the hash %HWX to save in the disk, and I can do this if I have a lot of clones of the hash! And I don't want that the user write: %main::HWX, since the hash need to have the idea of a global variable. The changes that I made in the gv.c works very well! What I want is to enable this in other Perl versions, because if someone want to port the resource of HWXperl to other Perl, it will be free to do.
