Hi all!
The bitwise operators patch by Thierry Grellier breaks Lua operator
precedence:
$ lua
Lua 5.1.1 patched (added | & ^^ << >> ~ \ !=) Copyright (C) 1994-2006
Lua.org,
PUC-Rio
> = 1 + 2^2 -- interpreted as (1 + 2)^2 instead of 1 + (2^2)
9 -----------> should be 5
>
I'm using Lua 5.1.1 as a base and the
http://lua-users.org/files/wiki_insecure/power_patches/5.1/newluaoperators.patch
from 2006-Oct-10
Anyway, I have found the patch very useful when interfacing with binary
data.
Thanks,
