You just failed to notice that I wasn't using .each. :) > > Je vous en prie, ne nous moquons pas de la langue francaise, qui est une > langue, apres tout, tres belle et subtile, et qui peut etre imbue de > douceur comme de violence avec de simples changements de nuance. Je ne me moquais point de la langue française ! Je ne voulais que dire qu'il est beaucoup plus possible de changer la langue Ruby que de changer la langue française.

Aussi, si je puis me permettre - le Francais est une langue, et Ruby est un langage (de programmation). Yet another one of those french subtleties! -- Posted via http://www.ruby-forum.com/.

You're using Array#size. I'm using Enumerable#count. They're not interchangeable. > Aussi, si je puis me permettre - le Francais est une langue, et Ruby est > un langage (de programmation).

If you think there's a valid technical reason why it's "impossible" to implement perhaps you'd care to state it. -- Tony Arcieri Medioh/Nagravision |
