lambda/proc/metaprogramming with Ruby

[Aldric Giacomoni]

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
