This corresponds to the expression construct EXPR in Kleppmann
and Beresford. It is used to construct a Cursor.
In contrast to the paper, Expr does not include the keys and
values operations which can be used to query the state of a
document. This simplifies the evaluation of an Expr which always
yields a Cursor.
