Haku is a natural language functional programming language I've created, based on literary Japanese.
I wrote and article about the implementation of Haku in Raku. You don't need to know Japanese or Haku to read it.
when you're not on mastodon, there are ways to simply write regular horizontal text and turn it vertical with css
if anyone wanted a screen reader to pronounce the japanese (which is very useful if you know some japanese but not every kanji) the pre hack would be a confusing mess
