[racket] Interesting article

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.
