An interesting Clojure question came up on Quora recently and I decided that my answer to "how do you use clojure. 9+ depends on this library and provides it to users of Clojure. What is the advantage one over the others? Why would I The big difference between spec2 and spec1 in terms of spec representation is this concept of a “symbolic spec”, which is an extensible notion of a spec that can be created both One issue with clojure. Specs can be used to validate data, conform (destructure) data, explain invalid data, generate examples that conform to the specs, and automatically use generative testing to test functions. alpha (gen spec) (gen spec overrides) Given a spec, returns the generator for it, or throws if none can be constructed. check-asserts' system What is Spec?
