The following code​:

  grammar grr {
  token TOP {
  <line>*
  }
  token line { .* \n }
  }
 
  my $match = grr.parse('foo bar asd');
  unless $match {
  die 'oh noes!'
  }
  say $match[0].perl;

Results in the following behaviour​:

  Null PMC access in find_method('perl')
  in <anon> at line 1202​:CORE.setting
  in 'Any​::join' at line 1
  in 'Mu​::attribs' at line 1203​:CORE.setting
  in 'Mu​::perl' at line 1207​:CORE.setting
  in main program body at line 14​:parser.pl

Whereas it should it should return a failure, for there is no $match[0]

This now outputs​:
Any

It's been over a year since the original report; is this the new correct?
