There is an excellent talk called "Underscore, you're doing it wrong!". The talk explains how well designed param order with currying leads to very short and expressive code -- and how underscore missed the boat. This aspect of it should be interesting as it's related to this post. It's well worth the watch.

I was just about to post exactly this. Well worth a watch. It was this talk which finally made currying "click" for me. And serendipitously the topic is the improvements currying and swapping args can make to the underscore (or lodash!) API.

I even tweeted to @jdalton on announcement "hey lodash, you're doing it right" :)
