Awesome macros usage

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)

Advanced datastructures

• 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
