 +Fibers allow for transparent non-blocking I/O implementations of existing interfaces (such as PSR-7, Doctine ORM, etc.). This is because the placeholder (promise) object is eliminated. Functions instead can declare the I/O result type instead of a placeholder object which cannot specify a resolution type because PHP does not support generics.

-''Fiber::suspend()'' could be replaced with a keyword ''suspend'' that would be similar to ''yield''. The keyword statement would accept an optional expression that would be the suspend value and return the value used to resume the fiber.

 It is the opinion of the authors of this RFC that it is best to provide the bare minimum in core and allow user code to implement other components as they desire. If the community moves toward a single event loop API or a need emerges for an event loop in PHP core, this can be done in a future RFC. Providing a core event loop without core functionality using it (such as streams, file access, etc.) would be misleading and confusing for users. Deferring such functionality to user frameworks and providing only a minimum API in core keeps expectations in check. It is the opinion of the authors of this RFC that it is best to provide the bare minimum in core and allow user code to implement other components as they desire.

 As noted in [[#why_add_this_to_php_core|“Why add this to PHP core?”]], extensions that profile code, create backtraces, provide execution times, etc. will need to be updated to account for switching between fibers to provide correct data. As noted in [[#why_add_this_to_php_core|“Why add this to PHP core?”]], extensions that profile code, create backtraces, provide execution times, etc. will need to be updated to account for switching between fibers to provide correct data.
