I agree with most of his gripes. Addressing his points about vectors, I have a fairly extensive library of vectors functions on github
http://github.com/noelwelsh/numeric It has the same API for vector, evector [extensible vector], and f64vector. It could easily be extended to flvector but I haven't yet had the need/time. (Nor the time to properly package it.) I regularly write numeric algorithms (e.g. discrete cosine transform, which I wrote yesterday) in a functional system using this library. The code is written using a compile-time unit system, which is well ...err... something. API is below in case anyone is interested. N.
