Actually there are a number of truly global variables in Perl. For instance no matter what package you are in, $ENV, $^W, $_, etc are always the same.

You are correct. Camel III's glossary says:
In Perl, only certain special variables are truly global—most variables (and all subroutines) exist only in the current package. | [reply] |

FWIW, those truly global variables are really all in the main package. The language parser acts as if those global variable names were prefixed with main:: if no package is specified, no matter what package directive is in scope at the time.
