As a recent thread pointed out: "that's just the way it is".  An equals 
method just returns its argument:

class Person
  def name=(val)
    @name = val
  end

  def name
    @name
  end
end

p = Person.new
p.name =  "Alice"
puts p.name   #Alice

class Person

  def age=(val)
    @age = val
    return 20
  end

  def age
    @age
  end
end

p.age = 22
puts p.age    #22

puts p.age = 30  #30

Presumably, "that's the way it i" so that when you write something like:

x = p.age = 40

you can know that x will equal 40, although somewhat paradoxically you 
can't know that p.age will equal 40:

class Person
  def age=(val)
    @age = val * 0.80
     return "hello"
  end
end

x = p.age = 40
puts x   #40
puts p.age   #32.0
