When it's the same as 

P:\test>perl -e"'fred' => 1;"

A hash element pair in a void context?

    There is no "hash" involved here. It's merely a list. 

    perl -MO=Deparse -e "'moo', 'oom', 'zoop'"
'???', '???', '???';
-e syntax OK

      I've been reading to much Perl 6 stuff where Pairs are distinct entities. Your right. It's just a 2 element list in a void context which is being optimised away. Hence the '???'.
