Definitely.
I'm doing some polishing of the code and making it more general so that
it works with arbitrary sugar expressions too.
But yes. it will go in at some point today.

Thanks a lot; that seems elegant. Could one imagine that this goes into the
next version of Rcpp? That would be nice.

In the Rcpp 0.10.0, inst/include/Rcpp/sugar/logical/SingleLogicalResult.h
there is the code:
template
class conversion_to_bool_is_forbidden :
conversion_to_bool_is_forbidden{
Which obviously can't be instantiated.
Presumably the code should be:

Hello Dirk, Romain, JJ,
Very interesting-looking new release. Thank-you for all your efforts!

Does this depend on g++ and/or c+11 support? Or do you the do the

Ah. Things are particularly interesting if you want to deal with strings.
The code below implements a c++ version of match for character vectors.
beware it uses trickery related to tricking the write barrier (but not

We are very excited about Rcpp 0.10.0 which appeared on CRAN this morning.
The announcement text included in the package is below -- see in particular
the new vignette Rcpp-attributes.
We will probably provide more example in the following days and weeks.
