Detailed Description

A value the language can write out in full: what a literal is, and what folding a literal expression gives.

Recursive, because a list of objects of lists is a constant like any other. kInteger is kept apart from kDouble for the reason the grammar cares about: a count of values has to be a whole number of them.
