in reply to Split at specific spaces

Another way returning the split parts only:
perl -E 'say for split /\S+\s+\S+\s+\S+\K\s+/, "1 2 3 4 5 6 7 8 9"'
Or written shorter:
perl -E 'say for split /(?:\S+\K\s+){3}/, "1 2 3 4 5 6 7 8 9"'

    Neat!++ It never crossed my mind that /K would work with split.

    As a newbie I'm reading and deciphering your response. My reference material doesn't seem to mention "K" anywhere. Can you (or anyone) enlighten me?
