Just to be sure to well understand.

Option 1.

    define-process list-file-template (with filename)

will expand to:

     (define-public list-file-template
       (lambda (filename)
         (process
          ...)))

and option 2.

     process list-file-template (with filename)

will expand to:

     (define-public list-file-template
       (lambda (filename)
         (make-process
          ...)))


Right?

Instead of 'make-process', why not 'processor'?

You mean:

  (process list-template
     (with filename)
     (name ...)
     ...)

right?

I think, it is a good idea because it eases the learning process from
high-level Wisp to more Scheme plumbings.
