Implementing dynamic scope for Fennel and Lua

news.ycombinator.com Unknown 2025-12-25 14:49:58

I’m continuing my work on fennel-cljlib, my port of clojure.core and some other core libraries, focusing on porting missing functions and features to it. One such feature, which I sometimes miss in Lua and Fennel, is dynamic binding. The Lua VM doesn’t provide dynamic scoping as a language feature, and Fennel itself doesn’t introduce any concepts like Clojure’s Var . However, we can still implement dynamic scoping that works similarly to Clojure and other Lisps using the debug library. Most of

For many couples, the numerous options for birth control still come with plenty of hassles. But scientists are working on an alternative approach that might be more appealing for some: a non-hormonal male birth control pill with possibly very few side effects. The drug is codenamed YCT-529, and it’s being developed by the company YourChoice Therapeutics, in conjunction with researchers from the University of Minnesota and others.

Nearly a month ago, a mysterious object was seen hurtling through the solar system and later confirmed as an interstellar visitor traveling toward the Sun.

An Even Scarier Predator Hunted Giant ‘Terror Birds’ in South America

gizmodo.com Margherita Bassi 2025-12-29 16:00:44

Sometime between 16 and 11.6 million years ago, a young caiman came upon a tasty snack in modern-day South America. The meal, however, turned out to be rather ambitious, because the croc hadn’t come upon just any old prey. It was a phorusrhacid, a large carnivore in its own right, aptly known as a “terror bird.” The now-extinct terror bird wouldn’t have given in without a fight—unless, of course, it was already dead, and the opportunistic croc simply scavenged its dead body.
