flavor: n. 1. [common] Variety, type, kind. "DDT commands come
in two flavors." "These lights come in two flavors, big red ones
and small green ones." "Linux is a flavor of Unix" See vanilla.
2. The attribute that causes something to be flavorful. Usually
used in the phrase "yields additional flavor". "This convention
yields additional flavor by allowing one to print text either
right-side-up or upside-down." See vanilla. This usage was
certainly reinforced by the terminology of quantum chromodynamics,
in which quarks (the constituents of, e.g., protons) come in six
flavors (up, down, strange, charm, top, bottom) and three colors
(red, blue, green) -- however, hackish use of `flavor' at MIT
predated QCD. 3. The term for `class' (in the object-oriented
sense) in the LISP Machine Flavors system. Though the Flavors
design has been superseded (notably by the Common LISP CLOS
facility), the term `flavor' is still used as a general synonym for
`class' by some LISP hackers.
