Question --- Channel.consumeEach() (a suspend function) seems to be implemented internally as

for (e in this) action(e)

— which looks like it’s implicitly calling this.iterator() and iterating over the channel that way. I assume that can’t actually be what’s happening (right?) since Iterator.next() is blocking. Or does Channel.consumeEach() actually block?

Yep, they have a specific Iterator that can suspend to enable these syntaxes
