Aye. Generators are lazy - they don't run at all until you ask for a value. By contrast, this is unlike Go's goroutines, which are busy - they commence operation as soon as invoked and run until the first yield (channel put, I forget how it is spelled now). This can cause excessive CPU utilisation, but it handle for _fast_ production of results. Which is a primary goal in Go's design.
