Wouldn't it rather be nice if we had more detailed callable types instead?
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.
