 *
 * This is used as predicates in `DataStore.save()`, `DataStore.delete()`, and
 * DataStore sync expressions.
 *
 * ```
 * DataStore.save(record, model => model.field.eq('some value'))
 * ```
 *
 * Logical operators are supported. But, condtiions are related records are
 * NOT supported. E.g.,
 *
 * ```
 * DataStore.delete(record, model => model.or(m => [
 * 	m.field.eq('whatever'),
 * 	m.field.eq('whatever else')
 * ]))
 * ```
