Ah, thank you, I remember that now.

Which raises the question: Why is this
"non-OO"? Why not str.integer (for instance)
instead of Integer(str)? Is it just to make
it more universally available (i.e., to 
different data types, Integer(non_str_obj))?

And why is Integer capitalized? I know of 
only four methods in the entire Ruby core 
that start with capital letters.

I sound like a five year old, do I not?
Always asking why...  :)
