  I'm not familiar with clojure or its libraries. Can you post some examples of well designed interfaces?

    If you're not familiar with lisps in general, it might be hard to grok the differences between lisp-macros (as used in Clojure) and "normal" macros you see in other (non-lisp [sans Elixir I think]) languages. But, if you are familiar already, and just wanna see examples of neat macros that makes the API nicer than what a function could provide, here are a few: - https://github.com/clojure/core.async/blob/master/examples/walkthrough.clj https://github.com/clojure/core.async/blob/master/examples/w... - https://github.com/weavejester/compojure https://github.com/weavejester/compojure - https://github.com/ptaoussanis/timbre https://github.com/ptaoussanis/timbre - https://github.com/krisajenkins/yesql https://github.com/krisajenkins/yesql Furthermore, macros enables APIs like this, that would be impossible to have in JavaScript for example: (spy :info (* 5 4 3 2 1)) => 120 %> 15-Jun-13 19:19:13 localhost INFO [my-app.core] - (* 5 4 3 2 1) => 120 `spy` here doesn't just print what the `` form is returning, but the form itself too. You wouldn't be able to achieve this without macros, as the evaluation of the `` form would happen before it gets passed to `spy`, so the initial form is already gone. Instead, a macro received the very code you pass into it, so you can print it, inspect it, rewrite it or whatever.
