First class callable for instance methods

[rela589n]

Description

Hi there!

I would like to propose following syntax sugar:

/** @var SurveyTemplate[] $templates */

$templateIds = array_map(SurveyTemplate::getId(...), $templates);

As the replacement for more verbose instance method call:

/** @var SurveyTemplate[] $templates */

$templateIds = array_map(static fn (SurveyTemplate $surveyTemplate): Uuid => $surveyTemplate->getId(), $templates);

Currently, first class callable methods allow to wrap only static method, while in current place non-static method is suggested to use.

Please, let me know what you think about it.

Also, If current feature is ever to be implemented, I wonder how would it work with property hooks, where no more do we have getters as methods

The first class callable syntax works with instance methods: https://3v4l.org/bBf4i

@Girgias I think the idea is to have first class callables for instances methods without $this. In their example, SurveyTemplate::getId(...) becomes a functino with one parameter, namely the $this parameter. That's the proposal, anyway.

Yes, that's the point
