Get the name of the currently executing method in Ruby

So $0 is the env variable for the top level Ruby program ... but is there one for the current method?

From stackoverflow

• From http://snippets.dzone.com/posts/show/2785:

  module Kernel
  private
      def this_method_name
        caller[0] =~ /`([^']*)'/ and $1
      end
  end
  
  class Foo
    def test_method
      this_method_name
    end
  end
  
  puts Foo.new.test_method    # => test_method
  

• Even better than my first answer you can use __method__:

  class Foo
    def test_method
      __method__
    end
  end
  

  This includes a : before the name which you can easily remove.

  Note: This requires Ruby 1.8.7.

  Kent Fredric : in `foo': undefined local variable or method `__method__' for main:Object (NameError)

  Mark A. Nicolosi : Sorry, this requires Ruby 1.9... I'll update my post.

  Mark A. Nicolosi : Make that 1.8.7: http://www.ruby-doc.org/core-1.8.7/classes/Kernel.src/M001072.html

  Kent Fredric : just my luck, still on 1.8.6 :)
