In the abstract I agree, but I'm not sure how easy it is and how much can really be shared. I think every language has slightly different rules about how (and where) a heredoc starts, so I suspect it'll be hard to share that part. And the "match the end" part is the easy part anyway, so there's a risk that sharing it may not bring very much benefit. Stefan
