The preprocessor is not gone. It still exists in the context of modules. Figuring out the details of that interaction has been a major issue when defining modules and the result is quite complex. I doubt that we will see clean modules that are free of preprocessor shenanigans, especially when writing any non-trivial portable library. I am no prophet, but I currently assume that unless we get hygienic module friendly macros and better conditional compilation on a syntactic level than dumb textual #ifdef, modules will only end up adding complexity in practice.
