Yes, only the first map passed into baz (only one passed in anyway in the
example) is kept, anything else is thrown away. Seems like a strange
example when something like this would have sufficed to get the point of

In my experience running the local clojure user group, a lot of clojure

paradigm switch (immutable data etc) and clojure's error messages.

I personally don't like this.
An atom won't suddenly change value without your knowledge because to get
its value, you must use @ or deref (which should be a big warning that,
yes, this value might change between calls to deref).
Adding sigils, in my opinion, adds to the noise and makes it harder

Hi everyone,

You could simplify your fix code a small bit by using go-loop and when,
like this:
