Clojure's destructuring is not the same thing as the "pattern matching" found in some other functional languages. Pattern matching can do various conditional checks, destructuring cannot. Clojure's "defn" supports destructuring in the argument list.
Full pattern matching is available in Clojure via libraries such as core.match: https://github.com/clojure/core.match –S On Monday, February 8, 2016 at 2:41:44 PM UTC-5, Laws wrote: > > Sean Johnson has a great video about pattern matching, where he suggests > that any function that starts with a conditional should have the > conditional removed and the conditional logic implemented as > pattern-matching and restructuring in the signature of the function.
