The /r/rust discussion has a pretty thorough analysis of the points made here.
Probably getting a lot of love right now because it times out for me.

Good post. Some problems just a lack of experience in Rust but others good complaints. I think the problem I sympathize the most with is that Rust is so anti array. I work with them a lot in unsafe code and it is a bit concerning that Fortran is still the best language when it comes to n-dimensional array manipulation.
use D for numerical computing, its as fast as Fortran, (almost) as easy as python, as flexible as C and as safe as Rust. see e.g. https://github.com/libmir/mir
