 A key is always a String.  You can use a Number, it will be converted to a
 String automatically.  Thus the String '4' and the number 4 will find the same
 entry.  Note that the String '04' and the Number 04 are different, since the
-Number will be converted to the String '4'.  The empty string can also be used
-as a key.
+Number will be converted to the String '4', leading zeros are dropped.  The
+empty string can also be used as a key.
