How to return self in Crystal

I'm a newbie in Crystal.

I'm trying to return self in Crystal, like in this Python:

class Something:
    def some_method():
        # do something
        return self

Here is a little extended example. say_hello is called by self.say_hello. Just defining self returns the object/instance itself, like expected.

% cat file.cr
class Something
  def say_hello
    puts "Hi"
  end

  def some
    self.say_hello
  end

  def some_method
    self
  end
end

s = Something.new

s.some

puts s.some_method

Output

% crystal run file.cr
Hi
#<Something:0x102b6de80>
