I don't want my C vars to be local but I want to be able to assign
values to them the usual way and not interfere with gloabal lua vars.
I set the "settable" method for the globls table but my method gets
called only when I assign to my C exported var(a userdata var that
is).That's what I want but is that normal or am I doing something
wrong?What if I set the setglobal and getglobal tag methods for my
userdata C vars?Wouldn't that do the job?

Should I switch to Lua5 now or will porting my code to it later be
easy.I don't want to mess with beta software unless I have to(there
aren't debian packages for it either I think) but I don't want to
rewrite the whole thing again later when lua5 is released.
