Neat but... Someone will make a crummier version of this in a language which doesn't feature parts looking like Unicode white noise and the original authors will be frustrated why the crummier vetsion took off and their project didn't.

Not every idea deserves to have an esoteric language attached to it to work.

Seriously, fonts that coders tend to use have included ligatures for quite a few years. For me, it’s less visual noise and a cleaner look.

I use Vim/Neovim and WezTerm but there are many combinations of editors and terminal emulators that support ligatures.

And many programmers fonts: https://github.com/ryanoasis/nerd-fonts
