[Newbies] Re: optimization (and late binding)

Thanks, I realized that it's not such true that a message sent to a constant value *must* return a constant value too.

Since message sends are late bound, it means that if you want to cache something, then you have to do it yourself.

I know (or I think I know) what late binding means, but I can't figure the connection with the topic of caching the return value. In other words: if st was NOT late binding, things were different about the to cache or not to cache some return value? Can you clear to me the idea?

molte grazie (= many thanks)
