wouldn't this approach of enclosing it again with /$re/g, as in this case, defeat the purpose of it?

No. $x =~ $y is already short for $x =~ m/$y/, so it doesn't add a penalty. And as per the last line of my answer, it's not stringified and recompiled when the entire pattern is a compiled regex, so the purpose isn't defeated.

As for marking as "solved", you just did :)
