: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).

languages of choice, although many hackers still grumble that

generation), and a prime example of second-system effect....
