Re: [Boost-users] Namespaces for Intrusive Serialization?

The concept of namespace isn't really applicable to member functions.
Member functions are invoked the syntax.

object.member_function(...)

The member function will be invoked regardless of the namespace
the object might have been delcared in.

non-member functions behave according to namespace rules
as you expect.
