You had me for a second. I even went back and checked
perlre to see how on earth the /x modifier would eliminate the fact that my RE will load $1 under one alternation option, and $2 under the other alternation option. Of course there's nothing there other than what I expected to find: that the /x modifier allows for whitespace and comments within regexes.
Are you suggesting that with /x it is somehow easier to determine which set of capturing parens loaded up the $1 and $2 special variables? Regular expression readability notwithstanding, I'm missing the point I guess.
The easiest solution I see to the counting problem is just to wrap the entire expression in an outter set of parens so that $1 captures both the right or the left side of the alternation.
But the point is moot I guess, since sauoq's answer seems to have solved the OP's problem in a more graceful way anyway.
