Hi

1.5 RFC:
https://wiki.php.net/rfc/true_async

Here=E2=80=99s the fifth version of the RFC with the updates made after the
1.4 discussion.

Starting from 2025-11-03, there will be a two-week discussion period.

**Changelog:**

* Added FutureLike interface methods: cancel(), isCompleted(), isCancelled(=
)
* Renamed Coroutine::isFinished() to Coroutine::isCompleted()
* Clarified exit/die behavior: always triggers Graceful Shutdown mode
regardless of where called
* Added rationale for =E2=80=9CCancellable by design=E2=80=9D policy: expla=
ins why
default cancellability reduces code complexity for read-heavy PHP
workloads
* RFC structure improvements: reorganized Cancellation section with
proper subsections hierarchy
* Moved =E2=80=9CCoroutine lifetime=E2=80=9D as subsection under Coroutine =
section
* Extended glossary with Awaitable, Suspension, Graceful Shutdown, and
Deadlock terms
* Introduced FutureLike interface with single-assignment semantics and
changed await() signature to accept FutureLike instead of Awaitable
for type safety
* Split RFC: Moved Scope and structured concurrency functionality to
separate Scope RFC. Base RFC now focuses on core async primitives
(coroutines, await, cancellation)

I decided not to wait until Monday and made the changes today. If
anyone has read version 1.4 and has comments on it, they=E2=80=99re still
relevant.

The Scope API has been moved to a separate RFC:
https://wiki.php.net/rfc/true_async_scope
