<?php
    public function addHandler(
        callable | string $event,
        ?callable $function
    ): void {
        if (is_callable($event)) {
            $function = $event;
            $event = '*';
        }

        if (!array_key_exists($event, $this->eventHandlers)) {

It seems like $event can also be of type callable; however, parameter $key of array_key_exists() does only seem to accept integer|string, maybe add an additional type check?

            $this->eventHandlers[$event] = [];
        }

        /** @psalm-suppress InvalidPropertyAssignmentValue */
        $this->eventHandlers[$event][] = $function;
    }
