I actually introduced the "put" command inside the function after the
initial docstring.  And it did work.

It would be useful to append another string variable to the initial 
docstring inside the function.  Avoids functions with long docstring
parts.

You were correct about the lexical binding part.

I had 

;; file.el
;; -*- lexical-binding: t; -*-

Does not seem the right way to call "lexical-binding".

Putting on the first line got the documentation correct.

;; -*- lexical-binding: t; -*-

But, perhaps it is not so good to include this undocumented feature.
