would the idea to be to rewrite every #() with Array empty? If that was the case could you get the compiler to do that as an optimization? I quite like the fact that #() is the empty array. it's nice and compact; quite aesthetic. cheers, Mike On Sat, Feb 13, 2010 at 11:06 AM, Stéphane Ducasse <stephane.ducasse@inria.fr> wrote:
Hi guys
chris mueller proposed in squeak to have
Exception>>messageText    "Return an exception's message text." +    ^ messageText ifNil: [ String empty ]! - -    ^messageText!
