Hmm... that didn't work either... it prints:
before: abcabcabc
after: "---".$1."---"bcabcabc
And re: security issues around executing any code, this is another reason I was hoping to avoid eval() or any of its close relatives!
As another possible idea, is there a way to precompile the replacement text of a regular expression, sort of like what qr// does for you with the search portion?
