in thread beginner question - why is hash key unquoted and in capitals

I have frequently seen code like: 

  my %magic_words = {
    PLUGH => "A hollow voice says",
    FOO   => "You are nothing but a charlatan",
  }

[download]

Which is an obviously-intended use for “barewords.”   Nevertheless, I have gotten into the habit of enclosing all literals in single or double quotes.
