Most (all?) code generators like missing declaration, create implementation, update signature, ... that need to print types fail on nested namespaces. This is a huge inconvenience to me as I always have to fix that by hand afterwards.

Reproducible: Didn't try

Steps to Reproduce:
test.h:
~~~~~~~~
namespace A {
namespace B {
class C {};
C* foo(C*);
}
}

test.cpp:
~~~~~~~~~~
#include "test.h"

// alternatively try with namespace A { namespace B { ...
using namespace A::B;

// create implementation for C* foo(C*);


Actual Results:  
A::B::C* foo(A::B::C*)
{

}

Expected Results:  
C* foo(C*)
{

}
