Now fixed in 4741028:
pmichaud@kiwi:~/p6/rakudo$ cat g.pl
grammar G {
token TOP {<letter> +% <sep>}
token letter{<[a..z]>}
token sep{\,}
}
say G.parse("a,b,c,d").caps.map({$_.value});
pmichaud@kiwi:~/p6/rakudo$ ./perl6 g.pl
a , b , c , d
pmichaud@kiwi:~/p6/rakudo$ Needs tests to resolve the ticket.
