Quoth perlmod:
"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."

On the namespace point, seems a bit harsh given the precedent in the
documentation.
