I experimented with the syntax for a while myself.  The only possible point of 
surprise I could produce is if a user wrote:

	package Parent {

		package Child {

... and expected a nested namespace relationship.  Perl 5's behavior here is 
no different than if you write:

		package Parent;

			package Child;

... but the existing syntax seems not to support that idea.

I'm not suggesting any changes to namespace visibility or namespace nesting.  
I mention this only to ask if the documentation should explain that no such 
namespace nesting exists.
