The default is no declaration. Only coders concerned about their use
of globals (e.g., people writing modules or large programs, or people
complaining about global-by-default ;) would add such thing.

Global declaration would be a purely syntactical thing. It does not
improve "security" in any way; one can always write "_ENV.x" to
access any global. It would only control the availability of a syntax
sugar. So, I think it is the one writing the chunk that has a say about
whether she wants or not the sugar, not the one using the chunk.
