I mean instead of simply defining a parameter type as `callable` we could specifically define what the callable expects. Something like this: ``` function bar ((int, string):bool $callback) {...} ``` A more generic approach that could be more descriptive, maybe. I have no clue if this was already discussed in other threads or not. And whether it is feasible to implement. Regards,
