It works well and there is absolutely no copy whatsover

#include <map>
#include <iostream>
 
int main(int argc, char *argv[])

You're wrong there. If it stores pointers then the pointers are copied; same as with a map of pointers. If it stores IMPs then the IMP must be copied; again the same as a map of IMPs.

I tried your code and it works fine.

You're using managed C++ aren't you? I use unmanaged C++ - I don't approve of managed C++.

Beside many tests failed to prove to me that C++ perform that much faster, so why bother
