I have implemented this under DOS using Microsoft Visual C++ version 
1.5.  I had the following problem with the example 

(in function change)

table["version"] = 1;

would not work (compiler said it was ambiguous) and had to be done as 

LuaValue temp(1);
table["version"] = temp;

I also suggest testing for the return value of Lua::dofile("name") 
which returns 2 if the file isn't found.

Cheers

John
