how can this be changed to correctly handle potential matches that overlap? How would you handle overlapping matches in a smaller string? The easiest approach is to apply each pattern to the string in serial. The slightly more complicated fix is to "back up" (via `pos()`) the length of the match - 1, then proceed with matching all in parallel. Either approach would work here. It comes down to your specific requirements.	[reply]
