I often find that the order in my source files often gets jumbled during development. It would be nice if there was some sort of automated action that could re-order the functions in the source file to match the order specified in the header file.

So, if the header file was ordered:

class Dummy
{
    Dummy();

    void func0();
    void func1();
    void func2();
}

Then the order of the functions in the source file could be arranged to follow suit

Dummy::Dummy(){}

void Dummy::func0(){}
void Dummy::func1(){}
void Dummy::func2(){}
