Who told you English was normal?
Of course natural languages have namespaces: they're innumerable and
flexible, and also form the ground of articulation, not the surface, and we
get to decide which to use when, both sending and receiving. If you're
really good, you can play on the available field of namespaces to create
things like jokes and irony. Think "semiotic field".

Who told you society wasn't massively fragmented?
Explicit namespacing (aside from being impossible) would only render the
illusion of communication even more untenable than it already is. I believe
logicians call this the problem of indexicals: in "this sucks!", how do you
know what "this" references? Very important in determining the attitude of

Do you mean "a means of scoping names, so that a local, apparently atomic
name can be mapped to a universal name"? Yes. Or do you mean "namespaces
as designed in the current rec"? Dunno.

Efficiency rears its ugly head. If you could derive the semantics from the
context, then you could just tell the computer what to do, in English.

Well, it makes life easier for language designers and implementers. Makes
life really hard for everybody else.

Who's gonna run it? Networking Solutions? What happens when somebody sets
up a competing registry? Who's going to settle disputes over the semantics
