You are making too many assumptions. The OP only posted one line of
code. That does not mean that $2 is not used in the next, in which case
it should be captured. And the OP only posted one example. The real
data may have more than one match.
Isn't one of the guidelines for this list is to prune code that has no
bearing on the problem?
Don't assume that only what is posted is the whole story.
