It's a very small price to pay.I've already indicated that my experience that sometimes, the price isn't small.
And if it is a price, then just change your qr{}'s to qq{}'s and done.That isn't so easy. Changing qr{$foo\d} to qq{$foo\d} isn't going to work.
But if it's so easy, you could start with qq{}, and change to qr{} only if you cannot debug your errors. Which would require no changes if you did things correctly the first time.
