JSConf 2015 Jonathan Martin
summary
Claims that native closures can be replaced by a small runtime that maps var/params to setter/getter/function helpers, implements scopes with a closure registry and prototypal forks, and is test-driven with mocha and chai; live codes a working polyfill and a transpiler at github.com/nibbler/closures; core API exposes s/g/F helpers and a stack-based registry, the implementation compiles to about 68 lines of code and the demo passes the specs so the approach actually works.
