Fw: What I'd love to see in Squeak
- 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.
(Disculpen que no lo traduzca).
