Until tonight I didn’t know anything about this issue - except that an old friend of mine is named Jacoby. I guess this is what you are looking for. Probably you find a solution in PDL. I don’t know.

But you might take a look at this. If I’m not totally wrong about what you want.

If I guessed right you might take a look at Is this a way to Go Perl #1.

And probably you find a "simple solution" for your problem or at least some further inspiration. And a serious use case to Go Perl.
