G'day Bod,

I provided some suggestions earlier.

On reviewing "Subs calling themselves", I see that ++roboticus posted some code that included Data::Dumper and $request.

If your current problem stems from implementing that suggestion, I'd look for typos there. It could be as simple as a '.' instead of a ',' in a list; e.g. you've concatenated a newline to another value in the list, rather than adding it separately to the list.
