C++ 2011 and __func__

So what happens to __func__ in different scopes? How about GCC's extension for pretty function names?

#include <iostream>
using namespace std;

namespace
{
  void f()
  {
    auto func = []()->const char *{ return(__func__); };
    auto func2 = []()->const char *{ return(__PRETTY_FUNCTION__); }; //GCC extension

    cout << func() << '\n'
         << func2() << '\n'
         << __func__ << '\n'
         << __PRETTY_FUNCTION__ << endl;
  }
}

int main()
{
  f();
  cout << __func__ << '\n'
       << __PRETTY_FUNCTION__ << endl;

  return(0);
}

Output:

/tmp> g++-4.5 -Wall -o test test.cpp -std=c++0x
/tmp> ./test
operator()
<unnamed>::f()::<lambda()>
f
void<unnamed>::f()
main
int main()
/tmp>

/tmp> g++-4.6 -Wall -o test test.cpp -std=c++0x
/tmp> ./test
operator()
{anonymous}::f()::<lambda()>
f
void {anonymous}::f()
