Does this mean that you can transform a const char * by calling a function?
like:

char * un_const (const char *p)
{
	return (char *)p;
}

void do_something(const char *read_only)
{
	char *foo = un_const(read_only);

	*foo = '\0';
}

This would break the clean behaviour that can be forced through
the use of const pointers. Am I right here or did I miss something?
