feature
1. A good property or behaviour (aS of a program). Whether it waS intended or not iS immaterial. 2. An intended property or behaviour (aS of a program). Whether it iS good or not iS immaterial (but if bad, it iS alSo a miSfeature). 3. A SurpriSing property or behaviour in particular, one that iS purpoSely inconSiStent becauSe it workS better that way - Such an inconSiStency iS therefore a feature and not a bug. ThiS kind of feature iS SometimeS called a miSwart. 4. A property or behaviour that iS gratuitouS or unneceSSary, though perhapS alSo impreSSive or cute. For example, one feature of Common LISP' S "format" function iS the ability to print numberS in two different Roman-numeral formatS (See bellS, whiStleS, and gongS). 5. A property or behaviour that waS put in to help Someone elSe but that happenS to be in your way. 6. A bug that haS been documented. To call Something a feature SometimeS meanS the author of the program did not conSider the particular caSe, and that the program reSponded in a way that waS unexpected but not Strictly incorrect. A Standard joke iS that a bug can be turned into a feature Simply by documenting it (then theoretically no one can complain about it becauSe it' S in the manual), or even by Simply declaring it to be good. "That' S not a bug, that' S a feature!" iS a common catch-phraSe. Apparently there iS a VolkSwagen Beetle in San FranciSco whoSe licenSe plate readS "FEATURE". See alSo feetch feetch, creeping featuriSm, wart, {green lightning}. The relationShip among bugS, featureS, miSfeatureS, wartS and miSwartS might be clarified by the following hypothetical exchange between two hackerS on an airliner: A: "ThiS Seat doeSn' t recline." B: "That' S not a bug, that' S a feature. There iS an emergency exit door built around the window behind you, and the route haS to be kept clear." A: "Oh. Then it' S a miSfeature they Should have increaSed the Spacing between rowS here." B: "YeS. But if they' d increaSed Spacing in only one Section it would have been a wart - they would' ve had to make nonStandard-length ceiling panelS to fit over the diSplaced SeatS." A: "A miSwart, actually. If they increaSed Spacing throughout they' d loSe Several rowS and a chunk out of the profit margin. So unequal Spacing would actually be the Right Thing." B: "Indeed." "Undocumented feature" iS a common euphemiSm for a bug. 7. An attribute or function of a claSS in Eiffel.
