I'm looking for some feedback on whether something like this is a good idea.
In my opinion, it makes the code more terse and easier to understand.

class Base {
    explicit Base ( const char* name ) : className( name ) {}
    const char* getClassName() { return className; }
    const char* className = "Base";
};

// Call Base class' constructor
class Derived : public Base("Derived") {
    Derived( int foo ) {}
};

// This would be syntactic sugar for calling the base class's constructor
for
// each of the Derived class's constructors.
class Derived : public Base {
    Derived() : Base("Derived") {}
    Derived( int foo ) : Base("Derived") {}
};
