#2It's nice to see languages converging on a standard set of features. String interpolation, random number generation, package management, etc.

Or apparently the even more common functional list operations: “map”, “for_each”, “filter”, “every”, etc.

#4The example for even numbers should be:
even_numbers = [1, 2, 3, 4, 5].find_all { |element| element.even? }
or
even_numbers = [1, 2, 3, 4, 5].find_all(&:even?)
instead of:
even_numbers = [1, 2, 3, 4, 5].map { |element| element if element.even? }

#5Or every language complicated enough is reinventing lisp partially.

If I'm writing ruby I'd prefer Array#select for this task.

#8Good post, although it served to remind me again how much I love Ruby for it's emphasis on being elegant and expressive. I may not reach for it first for anymore for standing up a new service, but I still use it for personal projects and scripts unless there's a compelling reason not to.

Exactly
[1,2,3,4,5].select{|x| x%2 == 0}
If I were interviewing a a Ruby dev, anything other than Array#select indicates lack of experience.
