Both array assignment and hash assignment cause the RHS to be evaluated in list context. wantarray can't tell the difference between array and hash assignment.

my @arr = get_it();
my %hash = get_it();

sub get_it {
  if (defined wantarray) {
    print wantarray ? 'list' : 'scalar';
  } else {
    print 'void';
  }

  print " context\n";

  return;
}

This prints "list context" twice.
