PATCH: cnumber - efficient access to C variables from Lua

[David Manura <dm.lua@...>]

I've posted the following patch against Lua 5.1:

  http://lua-users.org/wiki/CnumberPatch

The CNUMBER patch provides a more efficient mechanism for accessing numeric C
variables from Lua.  Accessing C variables becomes almost as efficient as
accessing local Lua variables.  Various design decisions were made, so I'm
interested in opinions on that and whether there is a possibility for this, or
at least something like this, getting into the Lua core.
