In? Method - Reverse Perspective Of Include?

Yes, this is lame, but I constantly find myself reverting to Python land where I used to test like this:

if this in that...

In Ruby, I have to reverse the perspective (which is hard for my wee little brain) and do this instead:

if that.include? this...

It occurred to me I can make Ruby do the thinking for me by extending the Object class. Thoughts?


class Object
  def in?(array)
    array.include? self
  end
end


Example use:


if 1.in? [2, 9, 1, 4]
  puts "Don't be so lazy, Tim."
end
