Apart from what Christian mentioned there are also "upvalues"
in the C api of Lua. When you add a C function to the lua
state, you can give it "upvalues", which are a bit like hidden
parameters that you can fetch later, when your function is called.
They are very useful for integration with C++ or for other forms
of OOP programming in Lua.
