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'
      > # wtf?!
      > say [1,2,3,4].elems
      4
      > say <1 2 3 4>.elems
      4
      $
