Then the book example needs to be fixed because the arguments are not
parsed by the custom join function.
Also, it is confusing the use of the extra word in "... This calls the join
function passed as extra with parameters ..." since there's an extra wiki
argument used for additional markmin render functions (to process custom
blocks), but that feature is not related to env.
