An “atomic” expression.

While atoms can wrap and contain other expressions, they never consist of several expressions chained together without any wrapping. For example, in [1, 2, 3], the child expressions are wrapped in the surrounding brackets; in 1.add, however, the child expressions are not wrapped. Therefore, a Tuple is an atom, while a QualifiedExpression isn’t.
