Can someone with a good understanding of the C++ standard tell me if
this program is legal C++
#include <iostream>
int x = 1;
int main(int argc, char** argv)
{
struct {
int operator()( int y ) { return x + y; }
} fun;
std::cout << fun( 7 ) << std::endl;
return 0;
}
It compiles and runs with gcc 4.4.1. I have done similar things in
other situations many times, so I assumed that it was valid.
But another compiler (not a version of GCC) reports:
error C2627: member function defined in unnamed class
I hope that other compiler is just wrong. But I'd like someone with a
better understanding of the standard to comment.
