Yes. iostreams overriding << and >> was pretty much universally seen as a bad idea and they eventually abandoned it in C++20/23 with std::format and std::print.

It's usually a good idea for operators to have a specific meaning and not randomly change that meaning depending on the context. If you want to add new operators with new meanings, that's fine. Haskell does that. The downside is people find it really tempting and you end up with a gazillian difficult-to-google custom operators that you have to learn.
