PointlessOne

I’ve found a few lines of code that make use of Rails’ method returning. I’ve seen it on the Errtheblog before and thought that it can be useful but someone will misuse it for sure. So here it is.

def feeds_list
returning([]) do |feeds|
BLOGS.each do |blog|
feeds < < feed_url_for(@app_name, blog)
end
end
end
Why do people do such things if there’s Array#collect

def feeds_list
BLOGS.collect do |blog|
feed_url_for(@app_name, blog)
end
end
