  Also heats up the room.

    Exactly. If the program won't read it (the printout) back, or unless it is designed specifically to sense the heat, then, strictly speaking, it's not a side effect (in the particular sense in which a side effect may reflect on the program execution).

  I don't know how F is implemented but in a lot of stack languages printing to the terminal isn't really a side effect. Every function takes the state of the entire world as it's one and only parameter and returns a new world.

  It also uses up RAM.
