Subject: Re: Iterating over an array n element at a time

Hi,

Sorry about the real newbie interrupting the high level thread, but...

I liked very much the "eachn" method from Martin, and decided to test
it out. I got a "Undefined method 'each_slice'" for the array. Went to
ruby-doc.org, and the core docs have each_slice defined in module
Enumerable. I have Ruby 1.8.4 installed. Does anyone know why is that
not working for me?

Thanks,
Marcelo Alvim.
