However if you wanted to save only a subset of the saved subexpressions, the ()'s around the match will let you use brackets to get a slice (but then you might be better off using non-capturing parens instead).

<nit>Maybe. You might have a large parsing regex that's been compiled with /o and you want the 3rd through 9th columns of 12 columns.</nit>

Your objection is valid but you shouldn't be using `/o` anymore. We have `qr()` now. Makeshifts last the longest.	[reply]
