Property-Based Testing with PropEr, Erlang, and Elixir: Unexpected appearance of a line of text in program code (page 147)

It is clear that the author meant that the existing code should be in this place. I think, it would be better for readers if this line of text began with a comment mark %.

Something like that:

% existing code is here
