Hi All,
From Lua manual :
"in particular, the number 0 and the empty string are also true"
so my question is there anyway to create lua that 0 an empty string become true ? is there any work or patch for lua source ? in Lua 5.2 this is possible ?

function empty(x)

    return not x or x == 0 or x == ''

end
