This can already be done today, using plain old modules and organizing your data structures in a way that makes sense. Separating business logic from UX logic concerns does not require rearchitecting how your application is structured, nor should it. In this case, the way to pay heed to Dijkstra's advice is not to *create complexity* out of fear. :) it could be that business logic belongs in Effects Managers.

Nah, these are both solutions in search of a problem. I sometimes wonder whether the actual root issue here is that I'm saying "you should just build things and then divide later in response to specific pain points" but that's a really boring (however correct) answer to what would otherwise be a fun problem to try and solve. ;) I'm not the only one saying this, by the way. Erik Lott is developing a large Elm SPA and his recent post <https://groups.google.com/d/msg/elm-discuss/u3J2eSThkjw/4FT3p50uBAAJ> echoes the same "this is the wrong thing to spend time worrying about" sentiment I've been repeating. tl;dr I hear you, but this concern doesn't materialize in practice. Elm has some things yet to work out (DOM APIs, how code splitting should work, etc), but architecture is not one of them. We're all set on that front, so let's go build things! :) -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.
