I've written a tiny gem called yes_i_did which adds a new method to your IRB session, yes. If you didn't quite get the name of something right in a command, simply invoke yes to rerun it with the typo fixed using the "did you mean" suggestion!
Setup is simple: just install the gem and require it in your ~/.irbrc.
This has already proven a handy time-saver for me, and I hope it can be for you too!
