Hello, Caleb.
Firtly, i’d like to point out that you aren’t the first person to come
up with the idea of combining assignment and pipeline operators, and
inroduce `|>=` operator
Take a look at discussion, https://news-web.php.net/php.internals/128141
. RFC draft is here
https://github.com/vadimonus/php-rfc/blob/main/ltr-assignment.md.
I haven't submitted these drafts as an RFC yet because I haven't
received enough positive feedback on the first RFC in the chain:
https://wiki.php.net/rfc/pipe_to_return. You can see another drafts in
github.
The main idea, is that pipe operator reverses traditional funcation call
reading order, so we need some more operators with same order to use
together to reduce cognitive load.
Your variant of this operator makes traditional rigth to left action,
like other action. But `|>` arrow visually defines opposite direction.
This may lead to incorrect perception, increase cognitive load and lead
to mistakes.
I think, all extensions of pipe operator should be ducsussed together to
intorduce non conflicting group of operators. Please add to your RFC
links to other discussions and theese RFC drafts.

Hi internals,
I'd like to open discussion on my (first!) RFC for the pipe assignment operator
(|>=):
https://wiki.php.net/rfc/pipe_assignment_operator
It adds a compound assignment form of the pipe operator, so that
$x |>= callable is shorthand for $x = $x |> callable, with
support for chaining. Implementation with tests is at:
https://github.com/php/php-src/pull/22633
Looking forward to your feedback.
Thanks!
Caleb
