The modules code in Rcpp (especially the 'code bloat') is responsible for a large chunk of the time spent during compilation, as the compiler has to do a lot of work to parse all of the generated functions.

What would we think about adding a defineRCPP_NO_MODULES (similar toRCPP_NO_SUGAR) that would allow users to disable inclusion of the modules code, for cases where they know they don't need it?
