Most definitely. I would like to see this changed in existing code.

Being a long time Ruby user, I always used $0 until
recently, Then I read some code by a new ruby user (whom I introduced  
to ruby).
I never bothered to see if an alternative to $0 existed.

You can learn from anyone. Even the nubies. :)
