I think many people here are programmers since stack sites started out as stackoverflow originally, which is about programming.
My question here is about the phrasal verb "to comment out". It makes a lot of sense to those who know that in programming you can easily turn some part of the code (usually a line) into simply a comment that would have no bearing on the code's execution. For example,
print: Hello world
can be easily turned into a comment in this way:
; print: Hello world
Programmers would say in this case, "I have commented out the line." It is absolutely logical and makes sense to me. However, I wonder if this phrasal verb ever was used before the programming came about. Did it exist in those times? If yes, in what situation it was normally used then?
