Lenses
Great article. But I'm wondering, how many of you have used Lenses in larger, or legacy projects?
It is this sentence that gives me some doubts:<p>> The formulation is wonky, and very difficult to grasp. Don't worry if the intuition hasn't kicked in. It turns out that you can use lenses quite a bit without fully grokking them.<p>Whenever I read something like this about a framework, I imagine that sooner or later some colleague will fall in love with the power of the framework too much and write code that is very hard to understand/maintain.
But I have to admit that I haven't worked much with Lenses myself yet so maybe things are not so bad?
