ruby - How to get the name of the calling method?

Question

is there a way in Ruby to find the calling method name inside of a method?

For example:

class Test
  def self.foo
    Fooz.bar
  end
end

class Fooz
  def self.bar
    # get Test.foo or foo
  end
end

Answer 1

puts caller[0]

or perhaps...

puts caller[0][/`.*'/][1..-2]
