Yes, I concur on most of these points and I've brought up some related points before. The operator overloading technique used by Rust is antithetical to efficient generic code. The core numeric traits and functions are currently designed only with built-in types in mind, causing BigInt (and others, e.g. matrices) to suffer. I don't know how to fix these things, but perhaps auto-ref and ad-hoc operator overloading (it works for Haskell, why not for Rust?) would be part of the solution.
Neither auto-ref or ad-hoc operator overloading would let you write a generic function that calls `pow` and works optimally with both bigints and ints. I think the only thing that would work is something like C++ ad-hoc templates, which is a road I don't want to go down.
Ultimately, I suspect that function overloading (the Rust trait double-dispatch trick above may be sufficient with auto-ref) will be of critical importance. This problem is very under-appreciated and I hope this aspect of the language is not stabilized by 1.0.
I don't think we should be trying to solve it. Patrick _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
