I'm thought more about this. The arrow should be avoided because ">" is
not valid HTML.
More significantly, I've come back to advocating the dot notation for

As a programmer, I think I can quickly check the top level name to see
what's going on. Already we have to look at $value and guess whether
it's a string, an arrayref or a hashref.
