Anyway to implement namespace or rename the $loader variable to something else?

We recently updated to the latest meta-box plugin (we were on 4.4) and we started getting a fatal error because another plugin was also using the $loader variable (instantiated in meta-box.php). In a future update, is there anyway you could make this variable a little more unique so this won’t hurt other sites that may contain a global $loader variable by implementing namespaces or renaming it to $rwmbLoader or something along the lines of that?

Thanks, and kind regards!
