Headers generated from interfaces uses invalid C++ when exported name has dot

[jackwasey]

The attributes vignette describes how to name a function using
// [[Rcpp:export(name="something.dot")]]
allowing use of . prefix or S3 methods. However, when
// [[Rcpp::interfaces(r, cpp)]]
is used, the generated header file uses the exported name (perhaps correctly), but when an S3 method is exported, the header includes things like:

    inline List rcpp.dot() {
      typedef SEXP(*Ptr_rcpp.dot)();

which don't compile.

To replicate:

Rcpp.package.skeleton()

Then change the attributes in src/rcpp_hello_world.cpp to:

// [[Rcpp::interfaces(r, cpp)]]
// [[Rcpp::export(name="rcpp.dot")]]

Then attempt to compile. I used devtools::load_all(). Without // [[Rcpp::interfaces(r, cpp)]] it compiles fine.

Lovely, thank you!

Lightning fast as always. Thanks.

That's Rcpp's slogan, isn't it? ;-)
