Quick reaction: that'd make sense to me! Adding a "use CurrentNamespace\Foo" or using "namespace\Foo" looks easy enough to adopt. Does this mean you're suggesting to use declare(symbol_lookup='global')? Or shorter: declare(lookup='global'), or maybe even declare(global_lookup=1) as I'm not sure we need 3 options here?
