Hi all,
I wanted to know the best place where I can find how instance_eval works. I
also wanted to know how the implementation of .each { } in implemented for
Array class.

I also need to say that I have been new to Ruby but old to OO programming.

Thanks.

ri instance_eval

also wanted to know how the implementation of .each { } in implemented for
Array class.

It's defined in array.c. It goes through the array and yields each
element in turn as it goes.

Here is how Array#each is implemented:
http://ruby-doc.org/core/classes/Array.src/M002225.html

Here is the documentation for Object#instace_eval:
http://ruby-doc.org/core/classes/Object.html#M000343

That should get you started.
