Well that certainly seems to do the trick.

This is exactly what I did.

It produced an error, but I was unsure of what to make of it. I knew  
that it would be obsoletified, and I thought there was some  
enumerator function that most people did. I didn't, and still don't,  
know how to use enumerators in this, or what they can even be fully  
used for. Help?

Apparently .split(//) puts things into an array. Did you know  
that?!?! I didn't know that!!!


>>> [a]
> => [1]

That's about five more things I just added to my ruby vocabulary :-D
