Yes, it follows.

When I use Emacs Speaks Statistics [], I like
all of my file buffers to be saved before evaluating any code in them,
so I wrote advice for 9 functions that provides this behavior. After
sharing that with the ESS list, one of the maintainers communicated to
me that in the development version of ESS there is a new hook that
will run when any of those 9 functions is called.

Since I'm on the MELPA version which behind that mainline dev version,
I wanted to write myself some code in my Emacs init file that upon
entering ESS mode would check if that hook exists, and it it does,
display a reminder to myself that I may migrate my code over to this
simpler approach.

Forgive my failures as a story teller; that is why I wanted to write that code.
