It has nothing to do with header files. Or real header file
problems.
Seriously, this goes against everything you learn as a
programmer, nothing should ever be typed twice and then to say
that the declaration and implementation could be different just
boggles my mind?!?! Great more work!
It is no different from overriding `interface` methods in class.
From the code structure point of view, declaration is interface.
Implementation is implementation. Keeping those separate may
sometimes/often be useful.
That said, I am strongly against permissive rules proposed in
this DIP. It should be similar to overriding rules - any smallest
difference between to signatures and program stops compiling.
Otherwise it is maintenance hell.
