ReturnValueMap uses identity operator (===) on parameters

ReturnValueMap requires that you use the same instances of all parameters defined by it when calling your mocked method. That's because the parameters are compared using ===.

ReturnValueMap.php:

public function invoke(PHPUnit_Framework_MockObject_Invocation $invocation)
{
    $parameterCount = count($invocation->parameters);

    foreach ($this->valueMap as $map) {
        if (!is_array($map) || $parameterCount != count($map) - 1) {
            continue;
        }

        $return = array_pop($map);
        if ($invocation->parameters === $map) {
            return $return;
        }
    }

    return;
}

I would like to be able to call my mocked method with parameters that are equal to those specified in my ReturnValueMap, but not identical (i.e. the way Parity does it).

Sorry, I just realized this is a duplicate of #318.
