Hmmm, okay, but now you've got another orthogonality
problem, because you can't distinguish between e.g.
a 5-bit signed int field and a 5-bit unsigned int
It might be better not to consider "bit" to be a
type at all, and come up with another way of indicating
that the size is in bits. Perhaps
'i4' # 4-byte signed int
'i4b' # 4-bit signed int
'u4' # 4-byte unsigned int
'u4b' # 4-bit unsigned int
(Next we can have an argument about whether bit
fields should be packed MSB-to-LSB or vice versa...:-)
