The following run shows how the fact that a list of captured
positionals barfs on an .elems call​:

  $ parrot perl6.pbc
  > rule Foo { (\d+) }
  > "1234 x" ~~ Foo; say $/;
  1234
  > "1234 x" ~~ Foo; say @​($/);
  1234
  > "1234 x" ~~ Foo; say @​($/).WHAT;
  List
  > "1234 x" ~~ Foo; say @​($/).elems;
  Method 'elems' not found for invocant of class 'ResizablePMCArray'
