For output, it's easy to hack the string metatable so that '%s =
%5.2f' % {'hello',math. pi} works as expected

see http://lua-users.org/wiki/StringInterpolation

getmetatable("").__mod = function(a, b)
        if not b then
                return a
        elseif type(b) == "table" then
                return string.format(a, unpack(b))
        else
                return string.format(a, b)
        end
end
