Update of List entries raises error

[topofocus]

ArcadeDB Version: 23.2.1

Expected behavior

A Hash or embedded document can be added to a list via

update #0:0 set liste = liste + { json }

Actual behavior

it raises an error

Steps to reproduce

create document type dat_document
CREATE PROPERTY dat_document.date DATE
CREATE PROPERTY dat_document.name STRING
CREATE PROPERTY dat_document.age INTEGER
CREATE INDEX ON dat_document (date) UNIQUE

create document type test_document
CREATE PROPERTY test_document.name STRING
CREATE PROPERTY test_document.age INTEGER
CREATE PROPERTY test_document.d MAP
CREATE PROPERTY test_document.emb EMBEDDED
CREATE PROPERTY test_document.many LIST
CREATE INDEX ON test_document (name, age) UNIQUE

INSERT INTO test_document CONTENT {"date":"2019-05-16","name":"hugi","age":97}
INSERT INTO dat_document CONTENT {"date":"2023-03-14","name":"Hugi","age":85}
INSERT INTO test_document CONTENT {"date":"1989-04-02","name":"Tussi","age":25,"emb":{"date":"2022-04-05","name":"berta","age":25,"@type":"dat_document"},"many":[{"date":"2022-04-05","name":"berta","age":25,"@type":"dat_document"}]}

update #18:0 set many = many + {"date":"2022-05-02","name":"Herta","age":84,"@type":"dat_document"}

ErrorMessage: Encountered " "+" "+ "" at line 1, column 32. Was expecting one of: ... ... ... ... ... ... ... ... ... ... ... ... ";" ... "," ... "," ... ... ... ... ... ... ... ... ... ... ... ... ... ...

However,

update #18:0 set  many += {"date":"2022-06-15","name":"Herta","age":23,"@type":"dat_document"}

works.

This seems to be a matter for the documentation!

@topofocus did you find the earlier syntax in the documentation? Please let me know so I can fix it. Thanks.
