Stef, I think that the issue on "readibility" is in the eyes of the beholder (a.k.a. zealot /du jour/).
From a cognitive POV having the variables 'created' and used as near as possible should make the code more understandable than having them all declared at the top of the method and used only (say as a temp variable within a block [worse if the variable is used as temp in two blocks...]). These issues (on readibility) are less strong in Smalltalk than other languages because ST is dynamic typed and the declaration is more often than not just the name of the variable. Also, ST promotes the creation of short methods and in the average we should be able to see more or less the same way the declaration of a variable be it at the top of the method or inside a block. OTOH, while the reality still strikes us with several large methods, then the ideas of having the declaration as near of the as possible are IMO a good move. my 0.019999... -- Cesar Rabak Em 04/01/2010 10:42, Stéphane Ducasse < stephane.duca...@inria.fr > escreveu: Hi guys in squeak a week ago nicolas pushed a cool (from my taste) changes that refactored the complete system so that |temp| declaration would be at the scope where they are used. This is not clear that this is an optimisation but I like the fact that temp are defined at the right place. Now it may lead to code that is a bit less readable in the sense that your temps are not systematically listed at the beginning of the method but occasionally in the closures that use them. From my hackish lisping state of mind I like it now what do you prefer?
