Great hidden feature!

I just tried this out for converting the libsodium headers into a 
.di file. It requires a little work before turning it into a .di 
(e.g. removing extensions) and then a little bit after (since the 
compiler generates code like `void someFunc(const struct 
someStruct* param1)`.

But after a few seds and a small D script to remove declarations 
I don't care about, it actually wasn't too painful compared to 
using something like dstep which is a 50/50 gamble on whether it 
works, and is a much bigger pain to automatically clean the 
output of.
