ожидаешь:
`(- 0 10)` -> `0 - 10` -> `-10`,
`(- 10 0)` -> `10 - 0` -> `10`,
`(- 10)` -> `10`
получаешь:
`(- 0 10)` -> `-10`,
`(- 10 0)` -> `10`,
`(- 10)` -> `-10` (какого чёрта?)

(нет, поведение, конечно, задокументировано, но мне это кажется непоследовательным)

#scheme

Учу языки задом наперёд, но да пофиг, в этом есть что-то забавное. Не древнейшие скобочки -> сворованные оттуда идеи в rust'е, а rust (с догадками, чем навеяны различные штуки) -> после него уже скобочки, где наиболее прямолинейно задействуются многие вещи, которые я уже видел в других местах (и которые, скорее всего, были изначально заимствованы из скобочек)

Did I tell y’all that it’s official now—my #Scheme standard HTML rendering r7rs-html5 is hosted on scheme.org! My work is recognized and available to y’all Schemers wishing for a good standard rendering!

Revised^7 Report on the Algorithmic Language Scheme

The report gives a defining description of the programming language Scheme. Scheme is a statically scoped and properly tail recursive dialect of the Lisp programming language invented by Guy Lewis Steele Jr. and Gerald Jay Sussman.

Got the inventory interface done ("done", yes I know Chainmail is too long), will finish implementing it tomorrow. SHOULD be ready to put up the update on Friday!

This is probably the first time I'm getting back to a relatively significant project I had abandoned before. This is whisper, my stab at writing a self hosting scheme to c compiler, originally bootstrapped from c, and it now has a REPL. It's still wildly incomplete but it's already self hosting and it has eval too now.

The eval compiles the expression into c and then creates a shared object out of it, loads it and executes it.

I found a way to enable square brackets as paren aliases on Kawa #Scheme! Here is an explanation:

https://gitlab.com/kashell/Kawa/-/work_items/125#note_3466499713

@PaniczGodek do you use quare brackets? What do you think of them?

Support square brackets [] as parentheses () alias (#125) · Issues · kashell / Kawa · GitLab

Many Scheme implementations support square brackets as alternative to parentheses, enabling a (supposedly) more readable syntax:

Published some Scheme hackery I was working on recently. One simple syntax change that can cut amount of code in a half or more.

Created a starter Emacs configuration to work with Guix!

Thanks to the parinfer Lisp editing approach, I think it's possible to create a configuration that's usable for newcomers unfamiliar with Emacs, Scheme and Guix.

Currently the configuration is in its very early stage, feedback and contribution welcome!
