Have you tried this?

Yes. (With a response that appeared in my post behind the "e.g." [that
you snipped].)

Do you get an error at sub() time, or when you later try to use re?

It seems to appear with sub(); in the snippet
    ...
    print "PRE"
    sub(/don't/, "do[", re)
    print "POST"
    print typeof(re), re
    ...
"PRE" ist printed but not "POST".
