in reply to using split delimiters

You are correct. In this example the ?: is dumb. I canít think of a case off hand where you would want to do that in a split, I donít think one exists.... Other monks please correct me if I am wrong.

    You may want to do it with something like /begin(?:block)?/ - note the question mark quantifier, or maybe in case of a backreference. I know I've needed this once or twice; it's not terribly common however.

    Makeshifts last the longest.

      If you needed it for a backreference though you'd use normal ( ) braces instead of the (?: ) braces seen here which are specifically intended not to store their results.

        Sorry, you are right of course.
