You keep adding conditions that lead you further and further away from 
any kind of connection with C programming. C programs are /not/ randomly 
scattered.

You mean it was organised? Like well-written C code should be? Good!

Then perhaps your counting rule applies to /you/, but that doesn't mean 
it necessarily applies to other people.

Yes. That's why I said it.

But C programs are not flies on carniverous Drosera (and you may quote 
me). What may constitute a limit in one sphere of activity need not 
necessarily constitute a limit in a very different sphere.

Well, I can, actually. Here's a line from a program that I've been 
developing recently:

double rate = get_interest_rate(acl->ac[acno].product_class, taxpoint);

I have no problem at all in reading the above. It tells me that I'm 
retrieving, for a given point in time, the interest rate prevailing for 
a particular financial product (product_class). acno is the loop 
control, and it indexes into a dynamic array of accounts, ac, for which 
control information (e.g. the number of elements in the dynamic array, 
and of course, the ac pointer itself) is stored in the struct pointed to 
by acl. By my count, that's an identifier that uniquely identifies an 
object, using four parts.

Ah! The light dawns! You have ten rules, so you must have a rule of one, 
a rule of two, a rule of three, and so on.

But that's unreasonable, because ten is an unreasonable number.

There are only four reasonable numbers in Computer Science, and ten is 
not one of them.

The reasonable numbers are:

0: it is reasonable that you can't do something (e.g. you can't have 
identifiers starting with a digit);
1: it is reasonable that you can do something exactly once (e.g. one 
entry point to a program);
INFINITY: it is reasonable that you can do something arbitrarily many 
times or make something arbitrarily long (e.g. in C you can have 
identifier names that are 30-odd characters long, which isn't going to 
impose a significant restriction on anyone, whereas in Fortran 77 the 
limit was 6, which /was/ a significant restriction, and thus unreasonable);
4: philosophically speaking, it is not reasonable to have an 
unreasonable number of reasonable numbers. The addition of 4 fixes this, 
provided only that you don't try to use it for anything.

That was easy.

So scrap your list and start again, and this time let the function 
dictate the form, rather than the other way around.
