Is there an equivalent Flow construct for the sequence predicates

any

and

all

? I need a way to short circuit a Flow if a value is ever found matching a predicate, similar to `anyMatch`/`allMatch`/`noneMatch` in the Java Streams API

This is the closest thing I found, but it seems like there should be a simpler way:

.firstOrNull { ... } != null

takeWhile?

(to replace any)

And all would just be a typical collect where you reduce the values, yeah?

actually you have reduce() already

reduce

wouldn’t work since it doesn’t short circuit. I guess

takeWhile

works, but it’s the same problem as

firstOrNull

since I don’t need the values themselves, just the Boolean
