Monkey patch to object to make for a nicer time of conditionals! Just install the gem and you're ready to go!

Let's take our class, Person:

class Person
  def initialize(name, age, sex)
    @name = name
    @age  = age
    @sex  = sex
  end

  def older_than_18?
    @age > 18
  end

  def younger_than_18?
    @age < 18
  end

  def male?
    @sex == 'm'
  end

  def female?
    @sex == 'f'
  end

  def me?
    @name == 'brandon' && @sex == 'm'
  end

  def geek?
    @name == 'brandon'
  end
end

So we make our person:

brandon = Person.new('brandon', 23, 'm')

...and do some comparisons!

brandon.all_of?(:older_than_18, :male, :me, :geek) # => true
brandon.none_of?(:younger_than_18, :female) # => true
brandon.any_of?(:male, :female, :geek) # => true

Simple to the point, no more mess of && or || checks for the same object.
