case to show it's required. What's going on: inside of Coffee-generated closures, calling `super()` is implicitly making use of `this` (or explicitly doing so if you look at the output code), so we have to pass `this` through closures as if `@` is being accessed within the closure. So, just add one more condition to the list in `Closure::literalThis`
…ntified as duplicates.
I'm not sure how we would test this, so... no tests.
