The problem with passing by stating that it's passed by reference is  
that there's the implication that this also confers in out status on  
the parameter. This is the case in C, however, it is *not* the case  
in Lua.

The easiest way to think of it is that all Lua parameters are only in  
parameters - at this point, the distinction between whether it was by  
reference or by value becomes mostly irrelevant.

It may be worthwhile, but any which way, such a comparison is unclear.
