This blog post shows possible ideas to make std.bitmanip.bitfields more
complete:
http://potential-lang.org/2010/07/02/quasi-quoting-ascii-art-to-define-data-structures/
An example of the ideas:
struct IntDesc_t {
...
immutable IST : 3 = 0;
immutable Unused0 : 5 = 0;
immutable type : 4 = 0b1110;
immutable Unused1 : 1 = 0b0;
dpl : 2;
p : 1;
...
That means allowing the fields to have an optional initialization value. And
they can be flagged to be immutable too :-) Bit fields that can't change are
common.
