      $ gawk 'BEGIN { print typeof(x["foo"]) }'
      -| unassigned
 
-'x[0]' comes into existence before it is passed to 'typeof()';
+'x["foo"]' comes into existence before it is passed to 'typeof()';
 'typeof()' cannot tell that it didn't exist prior to being called.

-not remain a scalar forever (or until deleted).
