Subject: Re: Why is there a seperate Math class?

I have to think this is the first time I've ever really disagreed with 
matz and don't really understand his logic.

If I were to ask someone for the length of the word apples, I would say 
"What is the length of apples?"  In ruby, this would be "apples".length.

If I were to ask someone for the sine of, say, 90, I would say "What is 
the sine of 90?"  In ruby, this would be Math.sin(90) even though the 
structure of the sentence is the same as for "apples" above.
