I went via "Atoms" in the expression section, then followed the links

It's a term that's used in the lisp and/or functional programming
communities, I believe. And I think I recollect that something similar
is used in (mathematical) set theory So it'
I borrowed 'display' from the formal definition of ABC. It's still used in
the quick reference: http://homepages.cwi.nl/~steven/abc/qr.html#EXPRESSIONS
. I hadn't heard it before and didn't think to research its heritage. I
like it for list/set/dict displays since it's rather a stretch to call

What I would like is if it were a lot easier for a person who just
saw a list comprehension for the very first time, and was told what it
is, to have a much, much easier time finding it in the Reference Manual.
Would a section on comprehensions in general, defining what a comprehension
is be appro

A display is a constructor that looks like a literal but isn't. It is
syntactically like the printed output, but may contain expressions to
be evaluated at runtime as well as compile-time constant expressio
So how do we get search to work so that people in the Language
Reference who type in 'List Comprehension' get a hit?

You come across something syntactic that begins by opening a square
bracket, and you know that its semantics are: "construct a new list".
That's what's common here.
What goes*inside* those brackets can be one of two things:
