You make an excellent point. I fall into more than one of the buckets you list, and it's definitely the case that there is unlikely a "one size fits all" solution here. However I just have this sense that there is an intersection of basic functionality for using "number types" that neither Rust nor the num crate really supports terribly well. Maybe I'll change my mind as I use it to build out some projects.
