Duplicate symbol when developed module is in installed global luarocks tree

[sewbacca]

I often find myself in the situation where I develop a luarocks module, which I already have installed in my global luarocks tree. Since I normally also add the global tree to my luarc, for autocompletion, it causes duplicate symbols all over the place. My workaround is to uninstall said module from my global tree, restart LuaLS and then develop the module. Does anybody has a better solution for this? Ideally I would like to ignore all classes loaded from a library, so it won't trigger duplicate symbols if they are found in an external library (but it still gives autocompletion for external classes).
