Using ADL, unqualified function names are looked up in the namespaces
in which the arguments to the function are defined.

Presumably if noncopyable were defined in namespace boost, then
function calls involving classes deriving from noncopyable would get
namespace boost added to the ADL scopes in which the function is
looked up.

Usually this isn't wanted, as noncopyable is an implementation detail,
not an interface.
