      Hola gente!

      Supongo que varios de esta lista estan suscriptos a las listas de Squeak. Me
      atrevo a reenviar este email de mas abajo, porque creo que importa a alguna
      discusion que aqui se planteo. Cada vez que vuelvo a leer las listas de
      Smalltalk, y de Squeak, en particular,
      surgen estos temas. Al parecer, son recurrentes. Hay otros mensajes con
      otros planteos bajo este mismo titulo en la lista de squeak-dev, pero ya me
      parecio algo de abuso reenviarlos a todos.

      Que opinan?

      (Disculpen que no lo traduzca).

      Nos leemos!
