Re: abstract method in Ruby
183800 [google@er kv] You can't call them *abstract* methods if you implement them
+ 183919 [ara.t.howard] how interesting!

    + 183958 [halostatue@g] Okay, Ara. Why do these methods need to be abstract and specificallyhave code around them? IMO, the *same* question should be asked oftsort.rb. I think that, in both cases, the answer is the same: theydon't.

    | 183994 [lukfugl@gm i] Umm, except, no. Maybe if we used Erik's "allocation-time checking"

  184002 [noone@no he ] file.each_byte.with_index.collect { |b, i| b + 1 }
