I ran into this before as well.  I was _very_ surprised to find
that #caller returned an Array of Strings (!!!).  Very disappointed,
I was really hoping it returned an Array of Objects themselves.
I ran into this same problem with Java and was disappointed (you
know, not being able to get a stack trace except as a string-based
value).

I was hoping to do something like:

class A
  def foo
    puts "A#foo"
  end
  def bar
    puts "A#bar"
    caller[0].baz
  end
  def baz
    puts "A#baz"
  end
end

a = A.new
p a.foo     # => "A#foo"
p a.baz     # => "A#baz"
p a.bar     # => "A#bar"\n"A#baz"

I don't know how useful this would be (or if it's possible to
cleanly implement) but it's something I tried to make work
at one point and gave up ...
