That depends on the nature of the combination.

I will likely never compile a C dependency with ImportC directly, 
and I will definitely never import a D module into a C project, 
but I have already used ImportC for some things and it really 
isn't that complicated either in implementation or praxis.

ImportC should've really happened 10 years ago.
