--- Comment #3 from Michal Malecki <ethouris at gmail dot com> ---
Just caught this one, too, something like:

if (x(a, b), c)
{ ... }

Where x is declared as

int x(int a, int b, int c = -1);

There should be at least a warning that "suggested parentheses around the
expression", not necessarily with every case where the "comma operator" is
used.
