The additions look OK to my eyes, except that I wonder what happened
to the idea of a short-circuiting exists?  Does exists necessarly
need to auto-vivify all the intermediate steps?  For example:

  $hash = {};
  warn exists $hash->{foo}{bar};  # false
  warn exists $hash->{foo};       # true or false?
