[edit] Example
module; // starts a global module fragment #include <string> export module foo; // ends a global module fragment // declares the primary module interface unit for named module 'foo' // starts a module unit purview export std::string f(); module : private; // ends the portion of the module interface unit that // can affect the behavior of other translation units // starts a private module fragment std::string f() { return "foo"; }
