+A list display yields a new list object. Its contents are specified
+by providing either a list of expressions or a list comprehension.
+When a comma-separated list of expressions is supplied, its elements are
+evaluated from left to right and placed into the list object in that
+order. When a list comprehension is supplied, it consists of a
+single expression followed by one or more "for" or "if" clauses. In this
+case, the elements of the new list are those that would be produced
+by considering each of the "for" or "if" clauses a block, nesting from
+left to right, and evaluating the expression to produce a list element
+each time the innermost block is reached.

+List comprehensions provide a concise way to create lists without resorting
+to use of the \func{map()} or \func{filter()} functions. The resulting
