We instead use: std::cout << fmt::format(...); for simple output, loguru[1] for everything else. I feel like the fmt grammar/mini-language is both nicely extensible and has hit the expressiveness sweet spot -- not too verbose (iostreams) nor too terse (printf). I also like that fmt has helpers for pointers (fmt::ptr), enums (fmt::underlying) and arrays (fmt::join). It's both easy on the eyes and feels consistent. [1]: https://github.com/emilk/loguru

Lightweight in software is a weird adjective. I used to assume it meant light on resources but after seeing what passes for "lightweight" I've disabused myself of that notion. Instead, I've seen it mean any of the following: not-much-ceremony-to-use (e.g. https://github.com/emilk/loguru) small amount of code but huge number of dependencies (e.g. micromodal https://github.com/ghosh/Micromodal/blob/master/yarn.lock ) But the common denominator appears to mean "feature incomplete".
