When I run this program​:

  my @​bar{1,2,3} = (1,2,3);
  my @​foo{map $_,1,2,3} = (1,2,3);

I get the output​:

  Can't declare hash slice in my at foo.pl line 1, near "} ="
  Can't use global $_ in "my" at foo.pl line 2.

I think the error reported on line 2 is confusing. I expect to see the
same error on line 2 as on line 1, since both lines are erroneously
trying to declare a hash slice with "my".
