lambda/proc/metaprogramming with Ruby

Hi all,
I'm looking for good tutorials which explain how to use the two tools of lambda
and proc (which, ideally, would also help me learn how to think in such a fashion).
I think that would solve the third issue as well: metaprogramming, aka writing
code that writes code.. But if not, do you know of a good tutorial for that as
well? :)

Thanks,

The best would be to read SICP (and watch the lectures).
Notice the wiki with the exercises translated in other programming languages.

SICP = Structure and Interpretation of Computer Programs

Regarding metaprogramming, I highly recommend Dave Thomas' "The Ruby
Object Model and Metaprogramming" series of screencasts. Very clear
explanations, nicely narrated. Dave uses TextMate to demonstrate code
snippets.

I agree. That series is simply excellent.

I also wrote a little bit about blocks and lambda on my blog a while
back:

Excellent - thank you to both!
Incidentally, James, I saw online recently your presentation for Little Big Ruby
and I really enjoyed it :)
