Still not a fan of this potentially not being portable between different 
compilers implementing the C calling convention on the same platform. 
But let's put that aside for a moment.

Let's say D bitfields are stored in memory in a non-portable way. How 
would a serialization library detect via introspection that these are 
bitfields and serialize them accordingly (in a portable way)?

In general, how to introspect on bitfields?
