@GeruzoniAnsasu 本质上，是你后一个 promise await 了前一个。相应地 Go 里面为每个 goroutine make 一个 channel ，在写结果前等前一个 channel 就行了：

in := make(chan func() any)
out := make(chan any, 1)

go func() {
for result := range out {
consume(result)
}
}()

prevDone := make(chan struct{})
close(prevDone)

for do := range in {
done := make(chan struct{})
go func(do func() any, prevDone <-chan struct{}, done chan<- struct{}) {
result := do()
<-prevDone
out <- result
close(done)
}(do, prevDone, done)
prevDone = done
}
close(out)
