Well, actually the manual says under `lua_pushlightuserdata`:

    Userdata represent C values in Lua. A light userdata represents a
    pointer, a void*. It is a value (like a number): you do not create it,
    it has no individual metatable, and it is not collected (as it was
    never created). A light userdata is equal to "any" light userdata
    with the same C address.
