@import std;
-The @import declaration above imports the entire contents of the ``std`` module (which would contain, e.g., the entire C or C++ standard library) and make its API available within the current translation unit. To import only part of a module, one may use dot syntax to specific a particular submodule, e.g.,

Enable the modules feature (EXPERIMENTAL).
``-fcxx-modules``
- Enable the modules feature for C++ (EXPERIMENTAL and VERY BROKEN).

``-fmodule-maps``
Enable interpretation of module maps (EXPERIMENTAL). This option is implied by ``-fmodules``.
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.
