Hi, i'm trying to code an 'option remember' in Ruby. This option should be used in order to save the result allready computed of a function. For exemple: fib=remember(:fib) transorm the fibonacci function in aO(n) function. I've tried a lot of things but nothing run, i've found nothing in the progmatic programmer and ruby in a nutshell books. Nothing in the RAA. Regards. -- Cedric Foll mïÍ: cedric dot foll at laposte dot net
