That's exactly what you should do and it does work, e.g.: user=> (set! *warn-on-reflection* true) true user=> (.meta ^clojure.lang.IMeta (proxy [clojure.lang.IMeta] [] (meta [] {:a 1}))) {:a 1}
In your small example you have two errors that might be fishy: a missing arg vector to pass to the super ctor and an extra `this` parameter in the method impl (proxy, unlike reify, is anaphoric and binds `this` for you) > On 30 Jul 2018, at 10:56, Mark Engelberg <mark.engelb...@gmail.com> wrote: > > Let's say I have a proxy object: > > (def p (proxy [MyClass MyInterface] (interfaceMethod [this] ...))) > > Now, I want to call (.interfaceMethod p).
