You can literally surround yourself with it, cover your desk, and easily move your eyes between dozens of functions. If you learn to keep order and stay oriented in that mountain of paper, you can be very effective.

That only works if your printouts aren’t too long, and contain the majority of the logic in your programs.

Today, the latter rarely is the case. Maybe, we need a way to print code with t selected documentation of called functions added?

That ‘selected’ would be a tricky problem, though. What I need to understand the code may not be what you need, or what I need a month from now.
