Eucalypt update. Slowly porting the Preact tests over one by one. As of today I managed to get an absolutely monsterous piece of code working where I can now run the Eucalypt test files (only the first basic test running so far) inside actual Reagent inside Squint inside Happy Dom inside nbb. This is so I can check canonical Reagent behaviour in the tests and make sure Eucalypt is conforming. Kind of hilarious that it works. I think I've already found a bug/difference between Reagent and Eucalypt behaviour.
