In C++, if you define a struct/class, and constructors apply for 
this.

struct Test {
    Test(const char* foo) {}
};

void cool(Test t) {}

cool("string"); // works


That works in C++, unless you mark that constructor with 
`explicit`


struct Test {
    explicit Test(const char* foo) {} // this opts out of the cool 
thing above
};
