That is pretty cool! Does this mean we could merge fcxx-modules into
fmodules flags?

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!).

**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.
