True.

But this isn't as compelling as it might be, since None is the only
one that enjoys common non-guru usage.  It only counts as consistency
if other people notice and remember the pattern.

The pattern people really care about is:

  C99:        true    false
  C++:        true    false
  C#:         true    false
  Java:       true    false
  JavaScript: true    false

(I can't find other case-sensitive languages with boolean types
to compare.)

I also think repr(false) should return a randomly chosen line from
an insults file.  This makes the interactive prompt funnier:

  >>> 1 == 1
  true
  >>> 1 == 17
  LIAR!!!
