I found these snippets:

<?php

interface FooInterface{}
final class Foo{}

class Container
{
    /**
     * @psalm-var class-string-map<T, T>

    public array $instances = [];
      
 	/**

     */
    public function setInstances(array $instances)
    {
        $this->instances = $instances;
    }
}

Psalm encountered an internal error:

Seems triggered by the missing template declaration:

Does it need template declaration? I thought class-string-map acts as a template by itself
