---------------------------------------------------- Exception#backtrace
     exception.backtrace    => array

     From Ruby 1.8
------------------------------------------------------------------------
     Returns any backtrace associated with the exception. The backtrace
     is an array of strings, each containing either ``filename:lineNo:
     in `method''' or ``filename:lineNo.''

        def a
          raise "boom"
        end
     
        def b
          a()
        end
     
        begin
          b()
        rescue => detail
          print detail.backtrace.join("\n")
        end

     _produces:_

        prog.rb:2:in `a'
        prog.rb:6:in `b'
        prog.rb:10
