Your "shift" is being mistaken for a bareword hash key symbolic reference (thanks, davido for the correction). If you say, 

    my %x = %{+shift};
# or
    my %x = %{shift()};

that will suffice. Anything to break up the bareword evaluation to an literal key identifier. Using strict and warnings will help spot that kind of thing.
