I haven't had a time to look at it in detail. It is sleek in the example I
just adapted to illustrate namespaces.  But what I dislike is that just
yesterday I managed to get back to the example from the Dec 20 blog post:

        int seed = RcppSexp(s).asInt();

That worked with the typedef.  I think that we owe "our users" more constant
behaviour in released interface.  Right now wrap() replaces this (and is
arguably nicer) -- but should we not keep the old stuff?

Ahhh yes. Had I read your email to the end before starting to reply ... :)

I think we should, even though it is code bloat.  But we introduced RcppSexp,
so now we are 'stuck' with it.  Can you whip the old interface back in?

Ok. There is no chance you will ever stop will you?
