I don't have the "assign issue to someone" provilege, but since
the issue hasn't been touched since June, I don't think you
risk others working on it too.

@soegaard So can I work on this issue now and submit a PR?

@Arya-Gupta

I don't speak for the Processing project, but yes.
In the end it will probably be @REAS or @shiffman that decides whether to merge your PR.

Thank you for your suggestion. We understand that the current syntax may not be entirely accurate, as identifiers and expressions are not technically considered "values". However, we believe that the current syntax is sufficient for beginners to understand the basic concept of the operator, which is to add a value to a variable.

Additionally, the use of more technical language such as "identifiers" and "expressions" may be confusing for beginners, who may not be familiar with these terms. We believe that the current syntax is more straightforward and easier to understand for the intended audience.

Therefore, we will be closing this issue and not implementing the proposed changes. However, we appreciate your feedback and will continue to review and improve the documentation as necessary. Thank you again for your suggestion.
