That wouldn’t mean “giving up” control of the language and its future.
Elm (programming language)
Elm is a domain-specific programming language for declaratively creating web browser -based graphical user interfaces.

Elm is statically typed.
Annotations exist on the line above the definition unlike C-family languages where types and names are interspersed. Types can refer to other types, for example a List Int. Redux Vue.

I’m not sure that could ever happen in the cazplicki ecosystem due to it being somewhat small and niche. Union types allow the programmer to create custom types to represent data in a way that matches the problem domain.
It can span multiple lines. For example, a List a is a list of values of unknown type. If Node was in its infancy when the io. Elm is purely functionaland is developed with emphasis on usabilityperformance, and robustness.

Unfortunately, delegating work does not come for free and a great deal of energy will be burned in people management. Code that produces or handles an optional value does so explicitly using this type, and all other code is guaranteed a value of the claimed type is actually present.
In a perfect world according to meElm would have people in its core team, with at least a few of those tasked with triaging issues and PRs.
That is, removing a function or changing its type can only be done in a major release. Free and open-source software portal. But trying to do that generalization in the first place is also why Elm has some really interesting potential in the long run than just another SPA abstraction.
