Cases of `RT/canSeq`

Why does `clojure.lang.RT/canSeq` need to check both `ISeq` _and_ `Seqable` when `ISeq <- IPersistentCollection <- Seqable`? static public boolean canSeq(Object coll){ return coll instanceof ISeq || coll instanceof Seqable || coll == null || coll instanceof

Private member variables for deftype

Is there a way of giving a type defined with `deftype` internal member variables? E.g. not passed explicitly in the constructor. With `reify`, we can use a closure : (let [ctx (atom nil) kv-store (atom nil)] (reify Processor ;; ... (in

Leiningen, AOT compilation, and classloaders

I recently ran into an issue with AOT compilation that I'd like to understand better. A minimal working example (MWE) can be found here . Basically, using `:aot :all` in `project.clj` with `lein trampoline test` results in different classloaders

`extend-protocol` order

Does `extend-protocol` guarantee order when used with subtypes? E.g. suppose class Foo implements interface IFoo. Then, extending both Foo and IFoo with protocol Bar: (extend-protocol Bar Foo (do-bar [] "Foo-bar") IFoo (do-bar [] "IFoo-bar")) Is calling `do-bar` on an object o
