compact

compact adj.  Of a design, describes the valuable property
   that it can all be apprehended at once in one's head.  This
   generally means the thing created from the design can be used with
   greater facility and fewer errors than an equivalent tool that is
   not compact.  Compactness does not imply triviality or lack of
   power; for example, C is compact and FORTRAN is not, but C is more
   powerful than FORTRAN.  Designs become non-compact through
   accreting {feature}s and {cruft} that don't merge cleanly
   into the overall design scheme (thus, some fans of {Classic C}
   maintain that ANSI C is no longer compact).
