It is particularly galling to see a correct algorithm criticized as
overkill when it is as simple and short as the above code segment.  There
may be a justification for writing code that only works part of the time if
the fix is costly and difficult.  However, it should be a general rule that
an algorithm which works in all cases is preferred over one that only works
in most cases.

Instead of panning someone's code because he has written it more correctly,
one should adopt the improved algorithm with gratitude.
