Cool, thanks for the explanation.

I noticed that it allows for values to be passed by reference. (also cool)

$multiplier = 2;
tap("5", function (&$value), use($multiplier) { $value = $multiplier * $value; });

The result will be 10

But if the callback return type is boolean (if it has a return value atall), it will simply return the first argument (the value)

Thx for the post.

Now, you might argue that it's less readable.

Yes, I do.

All examples you linked in the Laravel code base make it worst to read. All for the sake of removing a temp var? So in fn ($value) => $value is not a temp var? Not to mention the messed up call stack by anonymous functions. Sorry, I don't see the benefit.
