Req #79623 [NEW]: method_exists() is too strict in PHP 8

From: nicolasgrekas Operating system: PHP version: master-Git-2020-05-24 (Git) Package: *General Issues Bug Type: Feature/Change Request Bug description:method_exists() is too strict in PHP 8 Description: ------------ While working on making Symfony compatible with PHP 8, we're noticing a lot of failure that look like: TypeError: method_exists(): Argument #1 ($object_or_class) must be of type object|string, XXX given See e.g. https://travis-ci.org/github/symfony/symfony/jobs/690567745 Can we relax method_exists() and make it accept any value as 1st arg? None of the changes needed to remove these errors look valuable. This would lower the cost of migrating to PHP 8 for the community at large. (Symfony is just an early adopter here.)
