To check consistency ;) The macro assures that a Lua value either is not
a collectable object (that is, it is a boolean, number, light userdata,
or nil) or that it points to an object of the correct type. In normal
compilation, lua_assert does nothing (see llimits.h), so this macro does
nothing, too.
