I think it was Edgar Dijkstra but I am not quite sure. The purpose of these
leading semicolons was that you can easily see which closing bracket belongs
to which opening bracket as the semicolons make some sort of a line. Example:


if condition
then statement1
; statement2
; if other_condition
            then statement3
            ; statement4
            else statement5
            ; statement6
            fi
; statement7
fi
