OK sure, but where is the definition of "as good code as possible"?

It is opinionated.

Every person, so I expect, strives to write "as good code as
possible".

Let us look at `when' little:

- you place `when' when you need `nil' as last resort

- what if you change your mind in future and wish to modify function
  to return "" as last resort? You will need to introduce `if`
  function, you have to restructure it. You have to remove `when' and
  replace with something else.

- without parenthesis highlighting sometimes it becomes very difficult
  to understand what did `if' author intended to say? 

- multiple `if' statements one ofter other do not look nice and
  readable, and I have to use

- if you use `cond', you remain with `cond', but only change nil to ""

Some people write long functions, if, then, when, it is not nicely
indented, restructuring is difficult, what did author want to say?
Hard to think of it.
