Nailing methods, procs and blocks once and for all

[Eli Bendersky]

Hi All,

Is there a tutorial somewhere that clear away all questions that newbie
Rubyists have about methods, procs and blocks ? Most importantly:

- When is each typically used
- How are they converted to-and-from one another
- How they are used to express common functional programming idioms:
functions as first-class constructs, anonymous functions, passing
functions around, closures, and so on.

I think a single resource explaining this topic would clear much of the
questions that arise on comp.lang.ruby almost every week.

Kind regards,
Eli

Does this help?

There might be more on that Wiki.

Thanks, I will look into this.
In any case, driven by sheer curiosity I set out to write an article on
this topic. I will post a link once it's finished.
