Subject: 2Q: Getting first 4 elements from array and calling class methods directly

Hello fellow Rubyists!

I have written a quick n dirty code to display the first 4 RSS entries from a feed using "feedzirra" gem. The code is pretty straight forward: https://gist.github.com/4578863

I have two questions, related to this code:

1) Is there any more elegant[1] way to get the first for elements of '@entries' object array?
2) How should be defined the "feed_list" method in order to be called like: feed = NewsDisplay::feed_list

I know I should put a 'self' reference somewhere. A little explanation of who this technique works would be nice. I know that Class::method calls might be
deprecated in the future. However even "Class.method" looks much more elegant and I'd like to know how to implement it.

Best Regards,

[1] Elegant = Easy to read, concise code snippet. Cryptic snippets are not elegant imho.
