   Unlike with ``#include`` directives, it should be fairly simple to track whether a directly-imported module has ever been used. By doing so, Clang can emit ``unused import`` or ``unused #include`` diagnostics, including Fix-Its to remove the useless imports/includes.
 
 **Fix-Its for missing imports**
-  It's fairly common for one to make use of some API while writing code, only to get a compiler error about "unknown type" or "no function named" because the corresponding header has not been included. Clang should detect such cases and auto-import the required module (with a Fix-It!).

Clang can detect such cases and auto-import the required module, but should provide a Fix-It to add the import.
 
 **Improve modularize**
   The modularize tool is both extremely important (for deployment) and extremely crude. It needs better UI, better detection of problems (especially for C++), and perhaps an assistant mode to help write module maps for you.
 
-**C++ Support**
-  Modules clearly has to work for C++, or we'll never get to use it for the Clang code base.
