One advantage or Powershell though is that in it you can put something into the pipeline from anywhere in your code, even within imperative code like in the middle a loop, just by mentioning a bare value at nearly any spot. And traditional shells are the same way (though they only support byte streams output), where you can send stuff to stdout/err at any point.

But in nu, it's more like you're just dealing with collections as in most programming languages. If your collection isn't amenable to being generated by a simple expression like a map or fold, then you have to create a collection, prep the collection to be what you want it to be, then you return it.

In that sense it's really different from both Powershell and traditional shells, and more like just using a traditional programming language. So in Nu I miss being able to just "yield" a value from anywhere without staging into a temporary collection first.

This release added the ability to "yield" values via a generator fashion. It's called `unfold`, but will be renamed to `generate` in the next release: https://www.nushell.sh/commands/docs/unfold.html.
