Tbh, this is unreadable. Larry's example with an intermediate variable is a
magnitude times more readable. This is exactly why we need pipe operator.

It is not, the functions are being applied from in to out (or right to
left), which become hard to read with addition of each new function. Pipe
operator makes it natural as they are applied from left to right which is
how you read code, literally 0 cognitive load.
Just because someone _can_ do something doesn't mean that they should.

Why not? It clearly makes code more readable and in future with PFA (🤞)
will allow composing non-unary functions.
PHP is and always has been a multi paradigm language, there is no reason to
not add stuff which makes using functional paradigm easier.
