Unfortunately, it doesn't.

Not at the moment.

The dragon has no flame. If you use this how do you use (say) a slice? dtoh does this automatically by providing a templates struct, what does this do on the C side?

I can now verify that ImportC can import D files, and instantiate templates from those files!

Thanks for this solution! I will try to use this code for my project.
