Yes, interesting. Another thing that rose almost to an art form under the code was the double entendre. The old frothy romantic comedies are full of some very clever sexual analogies and hints that can be quite risque. Sometimes so subtle it takes 2 viewings of a film for contemporary minds to get it!
