I've been a programmer in real life for the past couple if decades., so I don't feel unqualified to respond to you here. Congratulations on your answer. However, dense one liners have a faTal flaw in the real world, they are not maintainable. Someone else, or even just you, has to come back and be able to Understand it, and to change Whatever the parts that go into it. For much the same reasons that premature optimization is the root of all evil, subpar clarity is too. It's better to waste white space than to over optimize or Over-stream.

You can't control the time budget that some future programmer is going to have when they come back to your code, and while streamed solutions are notoriously legible, they are very often equally immutable.
