Hi Tianfeng.Han,

Fibers will immediately benefit projects that use async I/O. This is not =
limited to amphp, but also includes ReactPHP, Guzzle, Symfony, and =
Psalm, to name that I am aware of that could use it in conjunction with =
I/O and multi-processing.

One of the ReactPHP maintainers and I collaborated on a proof-of-concept =
for ReactPHP, which is mentioned in the RFC: =
https://github.com/trowski/react-fiber

This fiber API was meant to be a lightweight implementation to enable =
user space green-threads/coroutines. I would love to see more async =
tools in PHP, but that will require much more work. This is meant to be =
a first step toward that eventual goal, without conflicting with or =
restricting future additions.

Cheers,
Aaron Piotrowski
