So \K basically means don't worry, I only started matching *here*, where here is the position where the previous atom of the regex stopped matching e.g 
my $str =           "foo bar baz";
# will 'start' matching here ^
$str =~ s< (?: \w+ [ ] )+ \K \w+ >()x;
print '[' . $str . ']';

__output__

[foo bar ]

Or should I just go back to implementing pointers in perl?

update: added missing whitespace in output (odd how an additional character requires so many to explain ;)
