Re: My Guile TODO list

[Ian Price <ianprice90@googlemail.com>]

Hi mark,

A lot of the stuff is pretty neat. I'm particularly interested in
changes regarding immutability, being a functional programming nut :)
I also greatly appreciate the work you have already done in improving
guile's numerics.

Like most people, I'll just pick a few to comment on

List processing is obviously very important, ideally when the native
compiler comes in we'll get some work in to reduce the number of
intermediate data structures built. It's been on my todo list, but I
don't know if/when I'd get around to it.

I'll look forward to that :)

Andy says that there are better hash functions on master. It doesn't
IIRC cover all cases, but it's a start.

:)

I had been putting this off, but I will do it.

parcomb works fine for most cases. I don't think this is necessary to
implement, unless you want to...

I've been working on this in my own time, on an as-needed basis. See
https://github.com/ijp/pfds/ . SamTH on #scheme recently pointed me to a
bunch of ones implemented for racket: ralists/fectors/etc. that I will
get around to adding.

> * Monad library?
I have a bunch of these already, mostly mimicking existing haskell
libraries. Generic operators are a bit of a pain, since you can't do a
generic return using GOOPS. This is motivating my experiments with
higher order modules.

> * Improve error messages and debugging
Always welcome.


Thanks for sharing.
