Answers why the lisp shines, killer features in action

• core.async - transforms AST into CSP programs
• cloroutine - suspends and continuations (coroutines)
• missionary - a reactive dataflow programming toolkit
• photon - realtime web, like Meteor, but for Clojure(Script)
• metaclj - staged compilation
• meander - transparent data transformation using datastructure pattermatching
• proteus - introduce mutable variables (don't use, just learn how to map your mind into immutable world)

• specter: an elegant API for querying and transforming nested and recursive data
  • meander: transparent data transformation (defined as pattern-matching)
  • Persistent AVL trees: persistent sorted maps and sets with log-time rank queries
  • Finger Tree: double-list, counted-double-list, counted-sorted-set
  • Hitchhiker Tree: create fast, snapshottable, massively scalable databases
  • Hierarchical set
  • Ordered: ordered sets and maps
  • Lazy Map: whose values are only calculated when accessed
  • Duratom: persisted atoms
  • Durable Queue: queue persisted on disk
  • bifurcan: linear map/set/list (stores entries contiguously in memory), ;writtern in java, but test suite (read: usage examples) in clojure
