No, it isn't very valuable, sorry to be blunt. I think you are following a
really wrong path here. You are trying to implement a C++-alike
object-oriented system in C. That makes sense as far as it goes, but if you
find yourself having to propose modifying the C compiler in a direction that
basically makes it speak C++, you might as well just use C++ in the first
place. You want the compiler to automatically choose one of several different
ways to initialise a union according to the data type of the argument you use
to initialise it with; basically, that means you want overloaded constructors.
So you should just use C++, which already is C with overloaded constructors.
And it also already has all the other features that you'll discover you need
in the compiler as you carry along this path.
By the time you get to the end of your journey, "coo.h" will be an empty
file and all the functionality will have been added to the C compiler until it
turns into a C++ compiler. I think you need to choose a different plan.
