<pre>I think that sample code below should cause compilation error because the
lambda function has a return-type "void" but it returns an "int".
#include <iostream>
int main()
{
auto G = [] {
static int x = 0;
return ++x;
};
std::cout << G() << std::endl;
}
According to C++11 starndard 5.1.2 p4, if lambda-expression does not include a
trailing-return-type and coumpound-statement has any statement other than
return statement, its return type is void.</pre>
