Agreed.  I'm trying to point out the issues that we've encountered
that "strongly encourage" less "human involvement" in the process.

E.g., trying to "force" MakeErrorCode to be placed at the right
spot in the file will, I *know*, lead to arguments over exactly
where that spot should be in each instance (IMO, "wherever it
becomes clear that this *is* an instance of the particular 'error'")

*You* have to come up with a solution that fits the size, personnel,
skill and discipline of your application/team.  If it works, great!
If it doesn't, tweak it (which is how *we* ended up going down this
road).

You would find our current approach, here, interesting.  Damn near
*every* "table" has been removed from the code and instantiated in
the database.  Couple this with lots of table driven code and
you magically expose (for modification) much of the software
without necessitating actually modifying the executables.

(the jury is still out on what the actual performance hit will be)
