Is there a difference between "acquiring" and "expressing" an eccentricity, from the point of view of an independent observer? Either way, if a person has an eccentricity, it's an indication that they're less likely to understand or care about conforming with "normal" ranges of human behaviour than average (unless the average person has an eccentricity, I guess...) in which case it seems reasonable to assume they're more likely than the average person to be eccentric in other behaviours.

Which doesn't mean the example isn't fictional, it just means I would expect someone who's entirely comfortable with referring to themself in the third person to be considerably less likely than the average software developer to worry that a variable-naming scheme that amuses them might be seen as a bit odd by the rest of the team.
