I had a look too. It is not as simple.
For now, I recommend you simply do /not use/ NA, NaN, ... for dates. I think
R catches a lot of that logic at the R level, replicating those tests and
special cases at the C++ layer is more involved that just passing an int or
float NA around. Maybe you can get by using Date(-123) (yielding a valid
date in 1969) or some other sentinel as a magic marker.
