Is there something similar to Java’s Stream.Builder? Something that I can pass around and let code add values to and finally create a Sequence? I mean I can always use a mutable list, but I like the smaller API of Stream.Builder.

yes, just use the sequence {} block

instead of "passing it down", have other code return their own Sequence object and use yieldAll. They're lazily evaluated, so it's pretty cheap to do so

Hm, thanks, When converting a large-ish Java code base this feels like too much refactoring on top of the already existing conversion. I guess for now I’ll stick with mutable list - or maybe create my own SequenceBuilder interface in top of MutableList.
