You can interpolate both arrays, but you have to do so at the right time 

print "@-:@+" 
  while 'the quick brown fox jumps over the lazy dog' =~ /(\b.+?\b)(.+
+?)\b/g

0 0 3:4 3 4
4 4 9:10 9 10
10 10 15:16 15 16
16 16 19:20 19 20
20 20 25:26 25 26
26 26 30:31 30 31
31 31 34:35 34 35
35 35 39:40 39 40

print "@-:@+"

Both arrays are reset before a new match is attempted, so when the match fails, they contain nothing to interpolate.

If I understand your problem, I can solve it! Of course, the same can be said for you.
