I think the biggest weakness in the ecosystem is that it's cumbersome to map between different approaches to immutability. I'd like to be able to use clojurescript for some stuff, reason/bucklescript for other stuff, and immutable.js for still other stuff without having to jump through hoops when passing immutable data around. Are there immutability constructs in flow or typescript that would allow libraries to conform to a type interface for conversion?
