> Reusing bit shift operators for IO is quite clever actually

It's a miserable trap. Operators should do something in particular, because of the Principle of Least Surprise. The reader who sees A + B should be assured we're adding A and B together, maybe they're matrices, or 3D volumes, or something quite different, but they must be things you'd add together or else that's not a sensible operation for the + operator.

When you don't obey this requirement, the precedence will bite you as, as it does for streams. Because you forgot, these operations still get bit shift precedence even though you're thinking of this as format streaming it's just a bit shift and happens when you'd do a bit shift...

Streams looks like something dumb you'd do to show off your new operator overloading feature, because that is in fact what it is. It should have existed like Mara's whichever_compiles! macro for Rust - as a live fire warning, "Ha, this is possible but for God's sake never use it" - but instead it was adopted for the C++ standard library.
