It could have been designed to have more traditional functions, but I find generators fit well into a language based on piping streams of values between functions. Usually, the distinction between a single item, a flat list, and a list of lists isn't important in Powershell, because commands are written with Powershell's behavior in mind. It's extra painful when it does matter, but it's a trade off against being more verbose every time it doesn't matter. Ultimately, it's personal preference; for an interactive shell, I like the tradeoff Powershell made, and I think it's a cool design space to explore, but I do think there's a lot of room to improve the implentation of the concept to make it less surprising and less painful to choose the alternate behavior when needed.
