Exploring C++ 20

Using Modules and import Declaratiopns

These files are extracted from the book verbatim. They require full support for modules, including import of standard library headers. Set the CMake variable MODULES to TRUE in order to compile these files. At this time (2020-05-10), no compiler release or prerelease can compile these files. I will try to keep this site updated as compiler vendors release more C++ 20 functionality.

Every chapter folder contains the files for that chapter, including CMakeLists.txt and test scripts. All files use POSIX line endings (newline only).
