Don't like the syntax

Agree

It just makes sense and also optional, so whoever doesn't like it can go back to using parentheses.

Syntax similar to default, without use statement and short for "return".

function($item) use ($baz) { $this->foo($item + $baz); return $this->bar($item); }

to

fn($item) { $this->foo($item + $baz); => $this->bar($item); }

It's like Accessors/Mutators in Laravel but native.

For me, the most important argument is that the pipeline pattern is a tried and tested pattern, that this RFC builds upon. A couple of examples:

• league/pipeline
• laravel's pipeline

This RFC adds syntax to make using these kinds of pattern much more convenient.

On top of that, there's the argument that multiple modern languages support a pipe operator:

• Hack
• Haskall
• Ruby
• Elixir
• And more

Finally, I've had numerous occasions where a pipe operator would simplify my own code — I have more than a handful real life cases where this would be useful.
