  I worked on/with bitfields in the past, the limit sizes is more 
or less for natural int types that D supports.

  However this limitation is kinda arbitrary, as for simplicity it 
relies on shifting bits, going larger or any byte size is 
possible depending on what needs to be stored, but ti's the speed 
that really takes a penalty when you aren't using native types or 
you have to do a lot of shifting to get the job done.

  What's the layout of what you need? I'll see if i can't make 
something that would work for you.

  Would be better if you can use a object that breaks the parts 
down and you can actually fully access those parts, then just 
re-store it into the limited space you want for storage, which 
then would be faster than bitfields (although not by much)
