Pretty cool. Could the following be used as a baseline to create the same functionality?

    async function * nextStreamEntry() { 
      while(true){
        const entry = yield;
        const result = await processEntry(entry);
      }
    }

    // Initialize the iterator
    const iter = nextStreamEntry();
    iter.next();

    // For every entry of the stream
    for (const monster of results) {
      iter.next(monster)
    }
