Banana problem
(From the story of the little girl who said "I know how to spell "banana", but I don't know when to stop").
Not knowing where or when to bring a production to a close (compare
fencepost error).
One may say "there is a banana problem" of an algorithm with poorly defined or incorrect termination conditions, or in discussing the evolution of a design that may be succumbing to featuritis (see also
creeping elegance,
creeping featuritis).
See item 176 under
HAKMEM, which describes a banana problem in a
Dissociated Press implementation.
Also, see
one-banana problem for a superficially similar but unrelated usage.
