Failing test case for covariant templates

[gsteel]

It is currently not possible to serialize types that are documented with @template-covariant

FYI: symfony/symfony#64130 but contributing to Symfony looks like hard work

Hey, thanks a lot for pushing this forward in Symfony as well! :)

It's worth mentioning that you can still annotate your stuff with

/** * @template-covariant T of MyType */class Some {
/** * @param MyType $things * @psalm-param T $things */publicfunction__construct(public$things) {}
}
