Visual Studio 2010 C++: Static objects imported via using directives in lambdas cause compilation issues! by srbr27

The following piece of code causes a C2065: 'cout' : undeclared identifier.
----------8<-----------------------------------------8<---------------------------
#include <iostream>
#include <algorithm>

int main() {
using namespace std;
int a[] = { 1, 2, 3 };
for_each(&a[0], &a[0] + 3, [](int i){ cout << i << “\n”; });
}
----------8<-----------------------------------------8<---------------------------
As per §5.1.2/3, the closure type of the lambda is declared in main. (Nit: `cout` being a static object and the capture clause being empty guarantees no capture takes place.) However, since the using directive should ideally make `cout` available not only to main but also to the lambda.

This issue is not reproducible in Visual Studio 2011 beta.
