This updates the code to work with the latest rust-nightly.
Wherever closures are taken I added a trait-bound by for the corresponding unboxed closure type.
The 2nd commit fixes up some issues where rustc did not seem to agree w/ nesting closures.
I ended up storing intermediate results and then calling the closure; not sure if there's a cleaner way to achieve this.
