compact

   1. (Or "finite", "isolated") In domain theory, an element d
   of a cpo D is compact if and only if, for any chain S, a
   subset of D,

   	d <= lub S  =>  there exists s in S such that d <= s.

   I.e. you always reach d (or better) after a finite number of
   steps up the chain.

   ("<=" is written in LaTeX as \sqsubseteq).

   2. 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 features 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).
