For me as an IS-ist 
  -- rather than should-ist or could-ist -- 
  it's simply not a point of what it `should' be compared-to 
   as we can't stop others from making silly or unflattering comparisons.

It CAN be used as a Domain Specific Language.

Heavy Sigh.
Alas, most of the would-be `free world' employs forced-assembly day-care 
concentration camps tasked, in the name of `education', 
with inculcating as-if `teaching'.
So I understand how you or most would have a teaching-centered worldview.

Have you considered a learning-centered, autodidactic approach?

If you could, the answer to the gist of your question might be "Here!"

Where IS elisp LEARNED?
Within.

Perhaps others would step forward with an elisp demo, tutorial, pro tip?

I'd like to believe that those of us wishing to LEARN elisp can learn from each 
other as well as rummaging around elisp manuals and intros in the process of 
self-paced, self-directed learning.
