Re: PHP True Async RFC

Even if you create a "Coroutine" class and allow defining a destructor, the result will be overly verbose code. I and many other developers have tested this. And the creators of AMPHP did not take this approach. Go doesn’t have it either. This is not a coincidence. > > It is, imo, a MAJOR FOOTGUN, and should not be even considered for implementation. > Why exactly is this a FOOTGUN? - Does this block lead to new violations of language integrity? - Does this block increase the likelihood of errors? A FOOTGUN is something that significantly breaks the language and pushes developers toward writing bad code. This is a rather serious flaw.
