It's such an easy restriction to work around that it just doesn't come up a ton on code that's always been written for 0.19. I imagine it was a monstrous hassle

It's such an easy restriction to work around that it just doesn't come up a ton on code that's always been written for 0.19. I imagine it was a monstrous hassle if you depended on it with a big 0.18 codebase, but the new JS interop (ports but more importantly custom elements) are very nice to work with tbh. There's a third inspired-by-elm language Derw (after Gren and Roc that are mentioned elsefork) but I don't know much about it.
