Yes, it is not a special case, it is just a usage.

Not true. One of the major uses of a function object over a plain function is that the FO can have true state (i.e. member variables).

Given that the restrictions have been covered above, listing cases (a few billion of them perhaps) where class and struct can be used interchangably seems rather pointless....

Please don't take technical discussions offline. That would beat the purpose of the forums.

If anything's off-topic or personal - PM use is justified. Hope you understand my positive intent. :)

Reply sent via PM, since it is no more relative to this thread than your post which I am quoting...

ps: The OP has still not enabled PM's....
