Ok, I was doing that, and it provides a good amount of information, but I guess what I'm asking is, is there any way to get a 'stack trace' like the output during a normal ruby error, like this?
```
1.9.3-p551 :004 > [].error
NoMethodError: undefined method `error' for []:Array
from (irb):4
from /home/stew/.rvm/rubies/ruby-1.9.3-p551/bin/irb:16:in `<main>'
1.9.3-p551 :005 >
```
