I agree with your opinion about keeping the abstraction layers
shallow, but in my view high-order and helper functions do not comprise
a new abstraction layer. For example in Lisp, using map, reduce (fold),
or any other high-order function is just like using for, or while in a
normal imperative language.
If I hit a call to map or to reduce, I've hit the bottom: map and reduce
are defined by Lisp and not by the programmer.
You truly don't know Lisp. *Everything* in Lisp can be _redefined_ and
if you can't do something conveniently that way, you can use a _macro_
to implement convenient new syntax for it.
