When @spritelyinst@octodon.social closes in on their work on #Guile's wasm compiler (maybe later this year?!), it'll certainly become the easiest way to target optimized #wasm. Tree-IL has gotta be the simplest intermediate language to compile to, and you get all the optimizations Guile offers for free.
Considering Robin Templeton, the author of Guile's #elisp compiler, is one of the engineers behind it, I can't help but speculate that this will put #emacs in the browser within reach. If I can handle my org-agenda online by 2025, I will cry.
It's called #Scheme because it allows just a few friends to plot a CONSpiracy to build amazing things.
