Seems in practice, whenever I have a need to do something with a String,
Hash or Array that isn't built-in, then I just tack it on, a la:

class String
  def every_other_char
    # yada yada
  end
end

... I don't ever subclass or wrap. And I love being able to do this -- this
for me is one thing that makes Ruby fun.

The risk with this, I suppose, is a name-clash with some other code that
also defines every_other_char and does something a little different with it
... but the scope of my work is limited to probably not ever have this be an
issue.
