Including core.cache in clojurescript?

I have no actual idea whether this is possible, but I would like to include core.cache in clojurescript. It might be the case that core.cache makes use of something that would cause it to be incompatible, I don't know, I am not at that point yet. Anyway

Re: Protocol specific type hierarchy

Michal: Thanks a lot. This is very helpful. I have not given much thought yet on the implementation, but there seems to be obstacles: 1. get the protocol method implementation dynamically (your suggestion solved part of it) 2. metadata can only be attached to symbols, not the types themselves.

Re: Using type hints to document return types

The problem with using type hints for doc is, that they actually alter runtime behavior, non - locally: - They replace expensive reflective method call sites with casts to a known type - Hence they effectively narrow the accepted type at the call site - They change the exception thrown in error cas

Hi *, I'm developing a Clojure bridge to the Alfresco APIs, where I use a protocol, Node, to extend a class coming from the original Java API (NodeRef). Now, one of the project contributors proposed to add type hints to the return values of the Clojure API functions, so to have, e.g.: (defn ^N
