This would work, but it's not going to be very friendly without automatic
cast support. Does the spec mention LSB and/or numeric conversions? Also, I
just noticed that B'0' is not equal to B'00', which also seems unfortunate.
Perhaps we could also add an LSB-last function, and output some kind of
warning when using numeric casts to the effect that the application should
use the LSB-last function because the casts will start using LSB-first in a
future version.
Alternatively, we could consider creating a new type that works as one
would expect:
- Automatic casting (sizes and numeric) - Automatic padding - numeric & text conversion - extract_bits using LSB as
position1.
and one of: - LSB on right - pad on left
or - LSB on left - pad on right
Another option: can we use some aspect of the type definition to specify
the LSB position to store in attyypmod?
