I’ve begun work on an implementation of Dhall in the Nim langauge. Nim is an imperative language that compiles to C and a few other C-like languages. I would say the implementation is half-complete, or at least complete enough that anyone interesting in Nim should wait rather than start their own implementation.

There purpose of creating a new implementation rather than use an existing one is to hopefully support performant functional-reactive-configuration. As far as I can tell the current bottleneck is backtracking in the PEG parser, but I should avoid focusing on optimization until I can fulfill the spec.
I looked at dhall-go quite a bit in the early stages, so thanks again to @philandstuff for providing an easy to read implementation.
I will announce again when the implementation is at least β-conformant.
