Thanks for your quick feedback everyone.

That is probably because it is very limited :) deliberately so.

The proposed syntax

$array |> array_map($fn1, ?) |> array_filter(?, $fn2)

When I compare to:

$array->map($fn1)->filter($fn2)

1. It's longer. Much longer.
2. It still requires knowing where the array goes. That's legacy which we
could sidestep with the arrow notation.
3. Admittedly, the pipe is much more powerful.

But why not both :) ?

Also, it would require accepting two RFCs although of course mine would
need to become an RFC too and longer term this is not a problem.

scalar_objects are wonderful. It's a space rocket compared to my
wheelbarrow. If it flies , mine is obviously moot. However, a wheelbarrow
is much cheaper and quicker to construct than a spaceship :D

Once again, what I propose here wants to be a simple, cheap to implement,
narrow quickfix. (Although users can add array_foobar($array, $arg1...) for
$array->foobar($arg1) as they need.)
