Re: writable "string" ?

I wanted such thingy for a long time too. It can be useful to build 
binary files too.

I understand that Gary don't plan to use this string in Lua, this is 
probably to dump to file at the end, or hand it to some library, etc.

Yes, it is probably the way to go. It can even have a toString function 
to convert it to Lua string...
Not hard to do, but some work indeed, that's why I never started this 
project... :-)
I vaguely recall somebody in this list announcing a similar library, it 
might be worth doing a little search...
