Users can achieve the same result pretty easily:

local cairo = require 'lcario'
local CAIRO = cairo

and then the same code ported from C:

cairo.set_operator (cr, CAIRO.OPERATOR_ADD)

That way you don't have to pollute the global namespace with several
symbols (you could even have no global symbol and only use require
return value). You can also put all constants in a sub-table to more
clearly distinguish them:

local cairo = require 'lcario'
local CAIRO = cairo.constants
