title: Avoid double concat in Ramda
body: <p>My question is simple. I started with <a href="http://ramdajs.com/0.18.0/index.html" rel="noreferrer">Ramda</a> recently, and I like it, for it is pure functional. I have a little issue with <em>concat</em> function, as it only accepts two lists as arguments. So, if I need to concat three lists or more, I have to chain functions like this: <code>concat(list1, concat(list2, concat(list3, list4)))</code> (for a four lists concatenation). Is there any better way to do this, that I don't know? Thanks.</p>
