I think the article is overly focused on small, pragmatic syntax issues without explaining how the underlying language and runtime have _enabled_ them.
It might be interesting to discuss _why_ keywords or maps or sets can work as functions, by implementing the IFn interface. Perhaps explain why homoiconicity and macros enable things like thread-first and -last, and talk about how we can implement our own reader literals.
