> At least have arrays as good as FORTRAN Yes. This is one reason why I simply didn't care to convert research code I was using for my research from the decade(s) old Fortran into C or C++, when I was in academia. I've been writing some machine learning products with Rust for a while now and I have to say I quickly abandoned using Rust for the computational components. The best way to use Rust is as it was meant to be: at the systems level, in this specific case for data and infrastructure code. Computation should be done using a language more suitable (e.g. Fortran) as one part of the pipeline. Rust is fantastic for writing pipelines that leverage other libraries for computation in this regard: the relatively strong static type system and easy error handling make it quite nice to work with.
