Getting the address of a table with a __tostring

[Geoff Leyland <geoff_leyland@...>]

Hi,

Has anyone got a better idea for getting the address of a table with a  
__tostring in its metatable than this?

> a = setmetatable({}, { __tostring = function() return "pretty but  
no address" end})
> print(a)
pretty but no address
> function rawtostring(t) local mt = getmetatable(t) setmetatable(t,  
nil) local r = tostring(t) setmetatable(t, mt) return r end
> print(a, rawtostring(a), a)
pretty but no address	table: 0x115150	pretty but no address

It works, but it's a bit mucky.

Cheers,
Geoff
