Specter: overcome your fear of nested Clojure data

on YouTube ↗42m

" summary

Specter is a Clojure library that actually navigates, queries, and mutates deeply nested structures and ships a pre-compilation step plus compiled-select/transform hooks. Examples show composable navigators like all/srange/filter and collectors that let updates use other values, and microbenchmarks show compiled selects near handwritten get-in speed and transforms about 5x faster than naive transform (compiled transform ~170ms vs manual ~150ms in the demo), so the thing is built and performs.
