<p>
<div>
<pre>The following code snippet (to my knowledge) should be rejected because the
overload resolution can't cope with the ambiguity of which operator() to call.
This ambiguity is described in [class.member.lookup] section of the C++
standard.
#include <iostream>
using namespace std;
struct IntPrinter
{
void operator()(int i)
{
}
};
class FloatPrinter
{
public:
void operator()(float f)
{
}
};
struct Printer: IntPrinter, FloatPrinter
{
};
int main()
{
Printer printer;
printer(55);
printer(55.1f);
};
The code compiles fine but should fail to compile. It doesn't compile on gcc.</pre>
