It should be possible to build a better PDL then PDL in p6. For one thing, you have better operator overloading. Perhaps more importantly, you can create your own operators. If you want, you can create a dot-product operator, ·. You can create new syntax for writing row and column vectors easily -- say (- 1, 2, 3 -) and (|1, 2, 3|). You aren't bound to mearly subverting the existing language as PDL does; you can create new bits of language from whole cloth.
