Re: Lua 5.1 Bytecode Question

[Tim Gogolin <tgogolin@...>]

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 :-(
