<pre>To help facilitate "const-poisoning" of the entire body of C (and C++) code out
there, I'd like to see a new warning, that would fire, when a pointer to any
object in any scope, that could've been marked as "const", is not.
For example:
size_t
mylen(char *string)
{
if (string == NULL)
return 0;
else
return strlen(string);
}
The above code would warn, because the function's parameter could be made
const. As the developer fixes the low-level functions to address the warning,
the higher level callers of these functions will start warning -- and that will
be a beautiful thing...</pre>
