I might be wrong, but your implementation just seems to check if the first
template parameter is a pointer-to-function type. Doesn't this break old
code that define a function<> returning a function pointer?

void (*)(int) MyFunc(void)
{ ... }

function<void (*)(int)> a = MyFunc;  // now it's broken!
