@waldoj My personal theory is that writing "foo", "bar", and whatever the fuck else tells other computer touchers that you too are part of some special nerd club, like you are in the know.
I wish to not guess what the fuck "foo" and "bar" are supposed to represent. I wish to immediately understand what the example code is supposed to do!
@Chuck_ORourke @chucker @Hawlucha @waldoj Not that the origin matters a great deal, it only distracts from the point that they are primarily nonsense words.
(Further evidence is that in programming vars it is often the nonsense foursome foo, bar, baz, quux or more. baz and quux have no “military origin”, no backronyms. Are about as pure nonsense from Dungeon/Zork as possible to find.)
(If the military origin were more “true” you’d expect foo/bar more in error examples than general examples.)
