Summary

Psalm is now able to properly understand something like:

object&callable(array):array

This would reduce errors with post processors being instantiated before being passed to the ConfigAggregator::__construct.

Example:

$parameterPostProcessor = new \Laminas\ConfigAggregatorParameters\LazyParameterPostProcessor(fn () => []);
$aggregator = new \Laminas\ConfigAggregator\ConfigAggregator([], null, [$parameterPostProcessor]);

This leads to an error:

InvalidArgument - config/config.php:45:50 - Argument 3 of Laminas\ConfigAggregator\ConfigAggregator::__construct expects list<callable(array<array-key, mixed>)|class-string>, but list{Laminas\ConfigAggregatorParameters\LazyParameterPostProcessor<array<string, mixed>>} provided (see https://psalm.dev/004)

To fix this, adding object&PostProcessorCallable and object&PreProcessorCallable to the annotation should fix the problem.
Something like this was also introduced in laminas-servicemanager with v4.0 and is supported by both psalm and phpstan.
