Maybe because a defined subroutine argument order will outlaw any possible parallelization effort which were at least planned for perl6. They specified ordering for lists and left the argument order unspecified, which is technically the best thing to do.

It all comes from LISP, which is the only other language which left it undefined, leading to possible parallel evaluation of lambda args, even if already nobody does it. Blame SICP.

cperl will never specify the order of subroutine arguments even if native threading as in perl6 is a very long shot. the proper 5.005 threading model which would have allowed fast parallelization is gone. and you can never trust p5p, as they usually have no idea about the background knowledge before 2001, so it is very likely that they will do as you want.
