I posted this on R-help and Dirk kindly pointed out that this list is a much better place for this sort of questions...

I was wondering whether anyone experimented with Rcpp and static variables. I remember reading that Rcpp is essentially stateless. That makes sense. However I just run a piece of code that contains a static STL structure, surprisingly  it seems that those static variables are preserved...

The question is, can we use static variable to reliably preserve state between Rcpp calls? If this is the case, this should be a better way to store state than by passing state variables between R and C++.
