I don't like spec. I liked the other one (by Mars I think that actually checks nested objects).

Perhaps I'm just stuck in my ways, but I like to be able to see in the code I'm looking at what attributes or actions are applicable to this thing. With Clojure I lose all of that. What is in this map? Well, I better print it out to know.

Clojure's dynamic typing, and any dynamic language to me, is only useful if you're never more that 2 stack frames away from your data's source. After that it's a lot of documentation to make sure you don't cock it up.

Well, with sufficiently good spec definitions you can know (and generate examples of) exactly what is expected to be "in this map".

Oh, spec also serves as documentation!

Maybe you'll like more now. :)
