$*ARGFILES is the correct FH to use when it comes to write unix filters
(as it was in the other examples of the page).

i recently read that >> could help here so i tried
seq 100 | time perl6 -e 'slurp.split("\n")>>.Int.sum.say'
5050
perl6 -e 'slurp.split("\n")>>.Int.sum.say' 0,21s user 0,03s system 155% cpu
0,151 total
nice ... but when x is ~ 75440 (not always), there is a problem
moar: src/unix/core.c:539: uv__close: Assertion `fd > STDERR_FILENO' failed.
perl6 -e 'slurp.split("\n")>>.Int.sum.say' 0,30s user 0,05s system 135% cpu
0,254 total
anyway: thanks for detailed and useful replies.
