Trying to emulate list comprehensions syntax I came with this syntax that resembles haskell list comprehensions (by having several guards separated by , and allowing zero guards):

> (1..24).comp { |x| [x, x.even?, x > 6] }
=> [8, 10, 12, 14, 16, 18, 20, 22, 24]

> [nil, nil, 1, 2, 3, 4, 5].comp { |x| [x, x != 4] }
=> [nil, nil, 1, 2, 3, 5]

> [nil, nil, 1, 2, 3, 4, 5].comp { |x| [x] }

=> [nil, nil, 1, 2, 3, 4, 5]

# Con archivos grandes tarda mucho hay que usar audios cortos
# hay otro ejemplo más completo en:
# http://www.stuartaxon.com/2008/02/24/playing-a-sound-in-pygame/
import pygame
import time

pygame.init()
sound = pygame.mixer.Sound('audiobook.ogg')

canal = sound.play()
