   featurectomy
      /fee"ch*r-ek"t*-mee/ The act of removing a feature from a
      program.  Featurectomies come in two flavours, the "righteous"
      and the "reluctant".  Righteous featurectomies are performed
      because the remover believes the program would be more elegant
      without the feature, or there is already an equivalent and
      better way to achieve the same end.  (Doing so is not quite
      the same thing as removing a misfeature.)  Reluctant
      featurectomies are performed to satisfy some external
      constraint such as code size or execution speed.
