Typical deductions are
- enums: E.max - E.min + 1 (this requires offsetting logic in
I guess a trait for this, say
enum bitsizeOf(E) = return bitsNeeded(E.max - E.min + 1);
is motivated aswell, if it doesn't already exists...

Ok, great. I'll try fixing this in a PR.
Further...I propose to enhance `bitfields` to automatically
deduce bitfield lengths in the following way.
autoBitfields!(ubyte, "x", 3,
Nordlöw:
wouldn't it be better to detect the mismatches between enum
bit-sizes and bitfield lengths at compile-time instead of at
run-time?
File an enhancement and/or submit a Phobos patch.
