c++ - Member function overload based on namespaced typedefed primitif types -

-

the following code fails compile g++ 4.8, in both c++03 , c++11

namespace n {typedef int a;} namespace nn {typedef int a;}  struct z {     void foo(n::a){}     void foo(nn::a){} };

the error 

d.cpp:7:10: erreur: ‘void z::foo(nn::a)’ cannot overloaded      void foo(nn::a){}};           ^ d.cpp:6:6: erreur: ‘void z::foo(n::a)’  void foo(n::a){}

i have thought types in different namespaces different types, no matter what. seems not. feel @ end compiler gets rid off namespace/typedef , focus on underlying type , clashes.

am right ? have workaround ?

types don't live in namespaces. names do. overload on types, not on names.
