If you use Test-Driven Development, you have the option to use Undo until the 
bug goes away. Try it; you will see what I mean.

On a big project, you might still sometimes need to debug. I have always used pp 
for trace statements, out of selected tests. Running them over and over again 
works so similar to debugging that you won't miss it.

However, someone here will have experience with the Ruby debugger and can answer 
your actual question. Any port in a storm!
