Ruby version is a pretty clear one-liner: validated_items = items.select { |item| is_validated?(item) } Though I'd expect a check for validation to be an instance method, so it'd probably look like: validated_items = items.select(&:validated?)

I don't find either of the Ruby versions clear at all. Both contain unnecessary syntax. Ruby seems to be going down the same path as Perl in trying to make all possible combinations of characters valid programs.

  my @validated = grep { is_validated($_) } @items; I'd argue the Perl version is clearer... assuming you know its syntax, that is.

  And if you are not programmer you can claim that == for comparison contains unnecessary syntax.

Even if it's not an instance method you can write the first as validated_items = items.select(&method(:is_validated?)) (Typed on my phone but I'm pretty sure that's the right syntax)

  It is! I'd forgotten about Kernel.method. Thanks!
