In addition to what benjaminva said, luv uses callbacks (like Node.js), whereas this uses coroutines. So for example with luv you might do something like:

    fs.readFile(filename, function(err, data)
      -- remember to check err
    end)

With this binding the code would look like:

    local data = fs.readfile(filename)
    -- err was raised if one occurred

With coroutines, you can use exceptions and for/while loops and they continue to work as you would expect.
