title: Is it possible to use functions from c++ namespaces with luajit ffi?
body: <p>I've got a lot of c++ code which contains a lot of functions and classes in namespaces (boost, for example).<br>
  Now I'm trying to embed LuaJiT2 as script engine, but I cannot find anything about calling functions and using other stuff from namespaces.<br>
  So, Is it possible to pass the functions from c++ namespaces to LuaJIT with the FFI?</p>
