labster: r: say ().item.perl
p6eval: rakudo 2441b0, niecza v24-35-g5c06e28: OUTPUT«$()␤»
labster: r: $()
p6eval: rakudo ba5e04: OUTPUT«No such method 'ast' for invocant of type
'Any'␤  in block  at /tmp/g2AQcfWj33:1␤␤»

Because $() is a special variable, it's not a good representation of
().item.  $( ) works, though.
