| + 147326 [wmorgan-ruby] I agree with you. I think this is bad behavior.
| 147348 [bob.news@gm ] I wouldn't be so certain of this. It's normal for operations like #dup and

| | | 147596 [wmorgan-ruby] I'm sorry, that simply isn't true, under any kind of reasonable

+ 147327 [matz@ru y- a] Why? I'd expect them to return instances of the class of the
+ 147329 [Ara.T.Howard] you suggest a has-a or aggregation approach then?
| 147360 [matz@ru y- a] It depends on what the original poster want to accomplish.
+ 147334 [sylvain.joye] This is a lisp-like language, so expressions are basically array of atoms
| + 147339 [twifkak@co c] Pragmatically, I'd suggest that you use the has-a relationship, as mentioned. Make the Array of atoms an instance variable of Expression, and give the Array an attr_reader. If you want to provide convenience methods that access the methods of the Array, that's fine, too. Modify the instance methods of Expression to act on the instance variable instead of on self.
| | 147343 [sylvain.joye] I'm not trying to talk about pragmatism (the program already works,
| | 147344 [twifkak@co c] Sure. Liskov's Substitution Principle states that if I (say, if I ever get around to finishing Ruby Quiz #35, let alone starting #36 :P) wanted to make use of an array (say, to store a list of captured pieces), you could construct an empty Expression object, hand it to me, and I could mess with it as an Array object, having no idea what "Expression" is.
| + 147346 [Ara.T.Howard] class Expression < ::Array
| + 147361 [matz@ru y- a] In Lisp, a sub-list from a list is a list (or atom), not an array.
| | 147362 [twifkak@co c] True... Array has a "copy constructor" (Array.new can take another Array), so you could call klass.new(theNewSubArray) unless klass == Array, instead of just massaging it into a klass...
| + 147365 [dblack@wo bl] Expressions may be arrays or lists of atoms and expressions in a
| + 147449 [halostatue@g] I disagree. In an OO language, a slice of an Expression should be an
| + 147454 [sylvain.joye] I don't. We're on the side of dogmas here, so no need to argue about it.
| + 147469 [wmorgan-ruby] I'd say that's probably a requirement for a well-written OO Expression
+ 147356 [wmorgan-ruby] But #+ returns an Array. Is that consistent?
147359 [matz@ru y- a] The result from + method is not a sub-array. Where X = A + B,
147440 [wmorgan-ruby] But I don't think it can be. To be initialized, #initialize must be
