A quick comment... This whole thing/discussion/war reminds me of the Squeak mailing list, long ago, in its worst days... Let's all take a deep breath for a second and put things in perspective : aren't we just talking about 2 (TWO) methods here? Is this a do-it-now-or-die type of decision? Can't we leave it as is for now and move onto something else ? Yes, Pharo aims at being a super-clean environment but there's enough crap still out there that we can surely delay that one (and think about it a little bit more) and clean something else! I guess that since I'm not a VM expert here, I'd have to rely on Eliot's suggestion and advice and knowledge. If he says it's a lot of work from a VM-building perspective, he must know what he's talking about. If he says it's a lot of work, he must mean "it's a lot of work". If he says it's *really* useful from a VM-building perspective, he must really "it's useful". He's built enough VMs in the past, he must know what he's talking about. Let's not allow this to become another "I-know-better-and-more-than-you" type of argument (or ad hominem attack) that flooded the Squeak mailing list a few years ago... My 2 cents. ----------------- Benoit St-Jean Yahoo! Messenger: bstjean A standpoint is an intellectual horizon of radius zero. (Albert Einstein)
