I've been programming for 35 years and I can say I've never once done this. Is this a thing?
In the time from that point until now, I can assure you that I have never, ever before heard the term "scotch file" or heard of any one describe such a thing.
So, two data points over 35+ years does not constitute a wall of fact, but I do believe it tends to cast a bit of doubt on the claim.
That’s got to be fairly close to universal among programmers who live the craft.
No?
