Hi guys, Am I the only one who finds the ruby protocol for accessing collections richer at times? In Smalltalk, if ary is an array, how do I get ary without its last element?
In Ruby, it's dead easy: ary[0..-2]. I can do that by heart after not having done any serious Ruby in a long time. In Smalltalk, I have to search through a long list of method names, because there are just so many possible names for the method. The point is: would it be totally out of reach to try and get a more concise and unified way to access sequenceable collections? I know I'm sort of asking for the slaughter of a holy cow: Smalltalk only has telling and easy message names all over. Or wait, does it? There's of course Class >> #methodName. And 2 @ 3 for points. Just to put something on the table, how about: (ary at: 1, -2) Or, without braces, if you don't mind the reversal: 1,-2 @ ary Or, consistent with current naming conventions: (ary from: 1 to: -2) Just my 2 cents, what do you think?
