<pre>This sort of thing is pretty alarming:
int counter = 0;
void f(int n = counter++);
and should probably get a warning. The author could've put written 'counter++'
in the body of the function instead.
There may be legitimate cases where the value is a function call (ie., int n =
get_the_default()'), so probably suppress on those.</pre>
