I think we can merge and it will be better if@dcdillon can add some change log.

Modifiedinst/NEWS.Rd. Hope that's what you meant.

Pretty much every repo has a fileChangeLog. Thought you'd noticed ;-)

Must be blind. I looked! Fixing.

Would it be reasonable to add a 'no_sugar' plugin so this can be turned on easily on a per-source file basis?

Maybe. I don't think I'd have use for it. Why would you turn sugar off, and why can't a#define before#include <Rcpp.h> do it?

Just looks cleaner than arbitrarily sticking#define in your.cpp files. Not a huge issue, just a thought.

I turn sugar off to get better handling of matrix operations without causing ambiguities in operator calls.
