This bitfield discussion came up in a DStep issue [1]. The bitfields 
mixin will generate a field to store the bits in, which I think was 
surprising for Russel. Although, currently there are no other way to 
specify which other field should be used for storage.

Another issue that came up is that you can use the default generated 
constructor or the struct initializer syntax to bypass the generate 
methods and set the underlying storage field directly.
