In my pre-awakening dream, I was living in a world in which CALL and LOOP statements in computer programs were considered signs of intrusion, so businesses had monitors, in the form of about a 1'x3' rectangular LCD display above their front door that alerted whenever either a subroutine was called or a loop was in progress. Accordingly, all "legitimate" programmers inlined their subroutines or did some other trick to avoid these two instructions. I was having a beer in a pub when one of the alarms went off across the street, and swarms of programmers were rushing over to help. I tried explaining to a guy walking in that I avoided the problem by using two PUSHs and a RET to avoid a CALL but he was studiously ignoring me.
