Same ideas are used in Nim's incremental compilation (wip) https://github.com/nim-lang/Nim/tree/devel/compiler/ic https://github.com/nim-lang/Nim/tree/devel/compiler/ic Also there are two JSON implementations with a flat architecture https://github.com/Araq/packedjson https://github.com/Araq/packedjson and https://github.com/planetis-m/packedjson2 https://github.com/planetis-m/packedjson2 (this one I wrote) But I agree it's a pain to write it like that.
