Summary
I was wrong in #2791 (comment). The
symfony/var-exporterpackage still exists in version 8.0, but does not provide the lazy objects trait.I'm allowing its installation, but throw an exception when
Configuration::setUseLazyGhostObject()is called.With Symfony 8.0, only the proxy manager and native lazy objects can be used. The bundle will default to native lazy objects.
It's a breaking change for people that uses
doctrine/mongodb-odmstandalone and callConfiguration::setUseLazyGhostObject(true). They will update tosymfony/var-exporter: 8.0.0and get an exception.
