Actually, they're even working on that. Because of new language regularization, grep (and map and part) will be a slightly different syntax in Perl 6:

    grep { block } <~ @array

Which allows for left-to-right pipelines:

    @in ~> grep { block } ~> @out

And, via unary ~>, allows for duplicates:

    given(@foo) {
        ~> grep { cond1 } ~> @out1;
        ~> grep { cond2 } ~> @out2;
        ...
    }

cond1 and cond2 do not need to be mutually exclusive (and probably shouldn't be, since otherwise you could use part).
