IMHO I was expecting more style without `defun'.

I do understand and get the point that in your examples while there
are many functions defined they don't just return the value but also
change various states, including they could be changing global
state. And that belongs to imperative programming style.

Though in Lisp it would be rare to find a program without `defun'
definitions.
