Here's MY opinion.

send should honor namespaces.

and other introspection features as well.

I think so.

One possible idea is making symbols to belong to each namespace, like
Common Lisp does, in that case,

  obj.foo(bar)

should be work as

  obj.<namespace::foo>(bar)

where <namespace::foo> means "symbol foo in that namespace", and its
correspondence can be modified by (dynamic) method definitions.
