Hi,
Your particular function could be expressed with a const reference. That
is:
int testReference(const int& input) {
int ret = input;
return ret;
}
(To see why it doesn't support non-const references, ask what you would
expect embind to do when C++ modifies an argument passed to it from
JavaScript.)
