TL;DR if you revise wording of the suggested change from "outside of a
namespace" to "before a namespace declaration", +1

Removing the ability "use" things outside a namespace is not acceptable to
me. I have often written quick scripts that use things from many namespaces
but don't belong in a specific namespace, and in those cases I usually
don't declare a namespace (it's also worth noting that you're never
"outside a namespace", you're just in the root namespace by default).

That said, placing the "use" statements before the namespace declaration
doesn't make a whole bunch of sense and should probably be explicitly
disallowed. The fact that it works in php-src at the moment is arguably an
oversight, if you try to actually *do* anything before the namespace
declaration you even get an error stating that it "has to be the very first
statement in the script" - so this case should probably be disallowed.
