Names should be short to save typing and clutter.  Of course, clarity also
matters.  I tend to prefer short names for frequently used language and library
constructs that everyone who has been using the language for more than two weeks
should know.  Longer names have their use in **your** programs and in less
frequently used constructs, where the overhead of memorizing what a short, unclear
name means is less than the overhead of typing a long name.
