        Except it isn't a script -- it's input that came from
the terminal, that got repetitively edited using vi mode, until it got
saved in a file so it could continue to be edited, and stay on the screen
while executing it in the original window.

        I.e. it's the natural evolution of input you type into
the terminal.

How often, when at a terminal, do you type #!/bin/bash before every line?

To have your script suddenly change behavior because you saved it in a file
and executed it by name would probably surprise most people.
