SRFI 201 and 202: a reference implelmentation and an invitation to discussion

Hi, A while ago I proposed a few SRFIs, in particular https://srfi.schemers.org/srfi-201, which provides extensions to core bindings (define, lambda, let, let*, or) https://srfi.schemers.org/srfi-201, which extends SRFI 2 with the capability of pattern matching Recently, with a second draft, I

Re: Shorter lambda expressions

I hope you don't mind me having dug this thread up, with an idea that is only loosely related with the original one. Recently I've been doing a small project in Clojure, and I've found that it provides a function called "partial" that performs a sort of partial application. With guile's curried

Hi Andy, I have been using soft ports to implement a text widget in my GUI framework. I also used GOOPS, which I regret to this day, and so the whole framework needs a serious rewrite, but if you're collecting various species to the museum of make-soft-port, you can have a look:

Hi, although I cannot be of immediate help with the topic, because I don't know anything about advection, I think that the main problem with your code is that it is imperative. While Python's stylistics handles the imperative code quite nicely, it looks rather strange in Scheme. >From my

Hm. Where's the difference to Guile's define? And why do you have double parentheses in your example? Still a bit lost. hmm...do you read the pasted code in the repo? ;-) Not yet, I must admit. But nevermind, got it. It looks like a definition for a parametric func or for a

Hi, My first impression is that the error might be caused by using the combination of #:allocation #:virtual and #:init-keyword for the colour slot. Since #:init-keyword initializes slot value with a given value, and virtual slots have no actual value, the semantics of such operation is rather

Inconsistent behaviour of the pattern matcher

Hi, I've traced something that is not entirely a bug, but which was a little surprise for me. It has to do with the extensions that guile provides to the Scheme language -- namely, uniform vectors and arrays. The (ice-9 match) module offers the syntax (match #(1 2 3) (#(a b c) (list a b c)))

Re: Fun with guile, Erastones + goldbach conjecture

Hey, I see that the style of your code is fairly unorthodox. I'd suggest you to read the following chapters of SICP, if you haven't already: Section 3.5 (Streams), which introduces the notion of streams, or lazy lists (that can be infinite), with the most amazing example of Erastostenes' sieve
