I just worked with it and the following simple read-eval-print loop:

# repl.ruby
while (1)
  begin
    print(eval(readline("")))
    print("\n")
  rescue
    retry  # restart from beginning
  end
end

via	ruby -r debug repl.ruby

To get all needed traceback frames, the minor change

*** mydebug.rb	    1999/07/13 17:19:34	1.2
--- mydebug.rb		    1999/07/23 05:46:40
***************
*** 303,309 ****
      end
  
      if event == 'raise' 
!       # @frames.push binding
        excn_handle(file, line, id, binding)
      end
  
--- 303,309 ----
      end
  
      if event == 'raise' 
!       @frames.push binding
        excn_handle(file, line, id, binding)
      end
  
is needed...

Oh well, a few more iterations on debug.rb, and we'll
have the *perfect* debugger ;-).

cheers,
