Thinking about device drivers I have written (not in C or Ada) it seems
to me that bit shifting is most likely to be the "manual" operation used
in low-level languages where the conceptually desired operation is not
supported.
For instance, if one has a numeric field that is supposed to be
positioned three bits left in a register the low-level approach
(at the source level) would be to "shift" and "or" it together
with the other bits before setting it into the register.
The conceptual operation is to store a field into a register-format
record before setting it into a record. The Ada method is much
more logical, except for those with lots of experience writing
drivers in lesser languages.
