i.e. trying to find a limited subset of functions that one can use to program 
in elisp and do non-trivial things but that do not involve searching the 
reference at all times.

I'm thinking like in standard learners dictionaries, there are clear 
indications, like asterisks, that tell the learner whether the word is basic 
(generally about 2000 words) or intermediate (about 4000 words).

People who know the basic words can get by and express most of what they need 
to express in daily life.

For ex, it is estimated that there are about 140k words in French, but daily 
use only requires 1k. Let's lower the number of passively known words to 40k, 
that's 50 functions in Elisp...
