So it got me curious, and I did a quick-and-dirty test implementation of scalar > file() and fstream() << scalar. But I get the "useless use of ... in void context" warnings.
So my tangential question: Is there a way to "export" the no warnings 'void' from inside the streaming package, rather than requiring it in ::main? It would be best if it could just turn off the warnings for the streaming objects, but leave the warnings on for non-overloaded uses of comparison and bitshift. I tried putting the no-warnings inside the overloaded functions, to try to keep the scope limited, but that's not the right place to prevent the warning. (Yes, I understand this isn't necessarily good practice, or "nice" to the external user. This is just for my own curiosity, and not something I'd put in practical code.)
