I forgot in the initial email, but there is also something changed in the header, as the reported register sizes do not match lua 5.0 sizes anymore.

Anyway, I think it would be a good idea to provide for a backward-compatibility mode.

I'm also interested in the response to this...
I write a lua "lint" like tool that works by analyzing byte codes and looking for unexpected global references. Whenever I pull a new lua version, that tool is always the first to break because the opcode numbers no longer mean what they did before :-(

Hi,

I saw in the source of Lua 5.1 that there are 3 new instructions:
1. the modulo instructions
2. the "length" instruction
3. the vararg instruction

I also saw that they were inserted in the middle of the list of isntructions of 5.0. I understand that you'd like the "MOD" op with the rest of the binary ops, but it makes things a bit harder when creating tools, such as a bytecode translator or something. Is there any chance any new ops are added to the /end/ of the list of instructions?

Kind regards,
