Can we leave the trolling out and concentrate on Rcpp isssues here?
This list has worked quite well this way for a few years, and I wouldn't mind
carrying on in that way.

Sorry, I'm at work with limited time for this, but how is that not simply a
roxygen bug?
You seem to start with a working file, you then add roxygen stuff, and it no
longer works.
If it were me, I'd try without roxygen. Or at least start from the existing
working roxygen + cpp examples, rather than trying a corner case of a single
'title' line.
