Hi folks, Just a quick note to mention an implementation of persistent (i.e. functional) vectors I wrote in celebration of the guile 2.0.6 release. It is written in portable R6RS, and tested on guile.
The code can be found at https://github.com/ijp/fectors It's a pretty short and simple module, and I hope it proves useful. I will note, however, that the library is not thread safe. It uses internal mutation to provide efficient access to the most recently used version of a fector. If this is a problem for you, or you are frequently using branches other than the most frequent, I also have an implementation of functional sequences based on fingertrees in my pfds library, on the fingertrees branch. See https://github.com/ijp/pfds/tree/fingertrees Cheers, -- Ian Price "Programming is like pinball. The reward for doing it well is the opportunity to do it again" - from "The Wizardy Compiled"
