This broke with as of 4.9.3, and was working properly in 4.9.2.

I found these snippets:

<?php

declare(strict_types=1);

/**
 * @template T
 */
class Set
{
    /** @var array<string, T> */
    private array $values = [];
    
    /**
     * @param array<string, T> $values
     */
    public function intersect(array $values): array
    {
        $intersectedValues = [];
        
        foreach ($this->values as $value) {
            if (\in_array($value, $values, true)) {
                $intersectedValues[] = $value;
            }
        }
        
        return $intersectedValues;
    }
}

Psalm encountered an internal error:

/vendor/vimeo/psalm/src/Psalm/Internal/Type/ParseTreeCreator.php: Cannot process colon without parent

@supersmile2009 it appears we're trying to parse the assertion string "in-array-T:Set as mixed". I think templates should have a special handling for in_array. Can you check if you can tweak your PR?
