Using GLOBs it is possible to directly manipulate the symbol table for individual entries, e.g.: 
sub foo { ... }
...
*foo = sub { ... }; # install new version of sub foo

Is something similar possible for an entire package, i.e. renaming a package? 
package Foo;
sub bar { ... }

package main;

*::NewFoo = *::Foo; # or something like this

NewFoo::bar(); # calls Foo::bar();
