"PIO_unix_pipe()" Leo's implemented a "PIO_unix_pipe()" method which allows you to run an external program and capture the results with a Parrot IO handle. He doctored the "open" opcode to use it
pipe = open "/bin/ls -l", "-|"
While that's right regarding above syntax snippet, the credits for C<PIO_unix_pipe()> belong to Melvin Smith, who'd implemented it in the first place. I did just (as normal) make it more workable. "Doctored" is ok, though ;)
leo - this is the usual "thanks for your summariies, Piers, but ..."
