Untangle your code with yield
summary
Generators in ES2015 are used to build custom iterables and to control async flow by passing values back into paused functions; the talk shows a working formatter that uses yield unwraps wrapper values to collect errors instead of throwing, salvaging translations and reporting two errors in the demo. It uses writer/reader style composition to avoid threading error lists and context through every call, runs in modern browsers and Node 6, and relies on Babel/regenerator with a regenerator 1KB runtime to support older engines.
