Please check back later.
Reorganize and reword the docs on atoms in parentheses, brackets and braces: parenthesized groups, list/set/dict/tuple displays, and comprehensions.
(Generator expressions and yield atoms are left for later.)
In the spirit of better matching the underlying grammar, comprehensions are covered separately from non-comprehension displays. Also, parenthesized forms (with a single expression) and tuple displays are separated.
All sections are rewritten to start with simple cases and build up to the full formal grammar.
