Just pay attention that when using later elements you don't need the
earlier elements, and you should be fine. (IIRC)

randomly-fn reads the commands first (that's why you need a macro in the
first place) so it prints 1 2 and 3 straight away. If you really need a

Monads are mostly used because they are necessary in Haskell. In
Clojure the urgent need is not there. However, you can sure get some
cleaner and/or more composable code if you use monads in your
advantage.

True what said, but sometimes I filter things on subject instead of
list as it is all the same for me (e.g. clojure and compojure-list on
the same label) and there it can be useful as well. Now I have

In the example, you can find a reference to the actual macro (line and name)
in the second part (Caused by:). By the nature of macro's I think this might
be not the most human way to get the line number, but surely the way the JVM
sees it.
