Proposed syntax to document the execution lifetime of callable parameters

[stof]

phpstan 1.11.x is adding new phpdoc tags to document the execution lifetime of callable parameters. See https://phpstan.org/writing-php-code/phpdocs-basics#callables for the documentation about them.

symfony/symfony#54654 (comment) also gives some background about why they have been added.

I'd like to have the Psalm opinion over those tags:

• does Psalm envision a need for such feature in Psalm ?
• if the answer is yes, is Psalm OK with the syntax defined in phpstan 1.11.x ? If no, what would be a suggested syntax (that phpstan might maybe adopt) ?

As a user of those tools and a maintainer of open-source package, I'm interested in seeing whether we might face interoperability issues if similar features gets implemented with different syntax (meaning my main worry is the case where the answers are "yes" for the first question and "no" for the second one).

Hey @stof, can you reproduce the issue on https://psalm.dev? These will be used as phpunit tests when implementing the feature or fixing this bug.
