comp.lang.ruby

Nailing methods, procs and blocks once and for all

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?

http://www.rubygarden.org/ruby?Closure...

There might be more on that Wiki.

Happy Easter

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.
