Right. Thus essentially a mix of the two recent tries, like the below, 
right? Patch becomes even simpler and more importantly we rely on 
c_inhibit_* only for c code proper.

If you think I'm on the right track, I will add the testcases, 
documentation, etc.

Is the name of the warning ok? It's a bit long...
