With more complicated examples, that is not so clear. See examples 
below. While I thought it was bad form to have to write optimisation 
hints for the compiler within the code. (That's what /I/ need to do with 
my unsophisticated compilers, but not what I expect of advanced C 
compilers.)

If it means writing code like this:

 > int getnumber( int * const number, int const min, int const top )

then that's a complete joke. Also consider calls like this :

typedef struct {char *p *q;} rec;

int** testfn( rec *p; char** x);

If these parameters are not written to, then presumably they would need 
to be written as:

int** testfn( const rec *p; const char* const* x);

(With that last parameter taking four attempts with Cdecl to get it 
right!) And maybe, in some cases it would need to be this:

const int* const * testfn( const rec *p; const char* const* x);

If people think this is clearer, then they're delusional. Then there are 
all the eight combinations of:

const char * const * const x
char * const * const x
const char ** const x
const char * const *x
char ** const x
const char **x
char **x

The last one is obvious, but what is anyone to make of all the other 
combinations? A bit of head-scratching is needed to understand what they 
even mean.

Another problem is that const doesn't do the whole job: have a look at 
those char* members of the 'rec' struct: they are not protected with 
const. It's not possible without changing the struct definition, which 
will make it extremely awkward to use the struct at all!

It's also possible to put together other examples where the type isn't 
spelled out directly, but is hidden in a typedef etc where it's not 
going to be possible to stick any consts in. So, type abstraction now 
has to be sacrificed.
