Martin Krejcirik:
I find the comma op useful somemtimes.
Please shows us all the cases you can think of (or coming from your own code, or coming from the Web) where you think it's useful.
This example shows absolutely nothing of comma wrongdoing.
See my precedent answer.
If anything, there could be a warning for passing signed value to unsigned argument (that caught me, not comma).
That's an OffTopic battle, for another day :-) Bye, bearophile
