Some of it has been :-) Check the lua-l archives.

Yes, that's the natural way, except that if "varname" does not contain a
number you'll get 0 and no warnings. You may want to use lua_isnumber before

Yes, there's a way: use user data and "getglobal"/"setglobal" tag methods,
but you'll have to program these.
The tolua tool is probably your best option here if you want to export many
variables, of many diferent types.
>In addition, how do I do the above with tables?
Again, tolua is very useful here because it handles structs too.
