Excellent! I was searching for this for a long time. 'what method called 
this method' or 'how to find out which method called this method ?'

So, here's one:

module Kernel
private
  def this_method
    caller[0] =~ /`([^']*)'/ and $1
  end
  def calling_method
    caller[1] =~ /`([^']*)'/ and $1
  end
end

Example:

def a
 b
end

def b
 puts "this method: " + this_method
 puts "calling method: " + calling_method
end

calling 'a' will output
this method: b
calling method: a

Thx!
