Enums are really nice substitute for integer constants instead of #defines.
Enums obey scope rules, #defines do not.
However enums are not widely used because of
1. tradition and style
2. awkward syntax required: enum { ABC = 123 };
The SATA layer uses enum for constants and while it was a bit of change
in style when I met it, it does seem to work just as well
Well, perhaps better, since there is some type checking, and where
auto-increment can be used finger checks don't generate duplicate values
or undefined holes in the value set.
Like the struct definitions vs. old K&R definitions, there is a mental
style adjustment to be made.
