Bug 13522: Make it explicit that scalar containd a hash ref

Prior to perl 5.12 keys can only operate on a hash. So although
$data[0] ( thats an abysmal variable name! ) will contain a hash ref
the perl compiler cannot deduce that from the context and gives
a syntax error. Add the hash sigil to make the context explicit and
the compiler can generate the correct code.
