The traditional way (ie C-like) would be

   ubyte[0] content; // zero-sized; use casts etc to access data.

as the last member. D supports that too, and just like
many other D features it works for ~80% of cases. IOW
you should be able to get it to work, but you might run
into problems if you need to access/manipulate such types.
