With a bit of fiddeling you can use every kind of bracket to basically make function calls in c++
Here are the links to the snippets, all compile and run

I'll jump on your unpopular side. With a decent IDE you should be able to point/click and decode what any operator is doing in any context. If I have two vectors, or quaternions, and I want to operate on them, why should I be forced to pass them to a standard function instead of clearly seeing what I'm doing. If you can't be bothered to know the types of your variables in a strongly typed language... IDK.
