Thanks for your response, very quick as always.
I'll try flvectors first.
It will be like writing fortran with racket syntax.
If you use for/flvector and in-flvector (esp. the extended in-flvector

Hi Russell,
You'll find examples of transactions in the tests for it:

It should be fairly simple to get working. Note that Snooze on Planet

Writing a book on Racket is an idea that gets kicked around
occasionally. It would be a major undertaking, and so only viable if
