"Clojure has good interop with java and that's what made Clojure explosive. If we can do that with Arc/Racket then we are better off for it."

Do we ever expect Anarki values to be somehow better than Racket values are? If so, then they shouldn't be the same values. (The occasional "interop headaches" are a symptom of Anarki values being more interchangeable with Racket values than they should be, giving people false hope that they'll be interchangeable all the time.)

I think this is why Arc originally tossed out Racket's macro system, its structure type system, and its module system. Arc macros, values, and libraries could potentially be better than Racket's, somehow, someday. If they didn't already have a better module system in mind, then maybe they were just optimistic that experimentation would get them there.

Maybe that's a failed experiment, especially in Anarki where we've had years to form consensus on better systems than Racket's, and aligning the language with Racket is for the best.

But I have a related but different experience with Cene; I have more concrete reasons to break interop there.

I'm building Cene largely because no other language has the kind of extensibility I want, even the languages I'm implementing it in. So it's not a surprise that Cene's modules aren't going to be able to interoperate with Racket's modules (much less JavaScript's modules) as peers. And since the design of user-defined macros and user-defined types ties into the design of the modules they're defined in, Cene can't really reuse Racket's macro system or first-class values either.

My comment is only a remark to "what holds back widespread Arc adoption".

If your goal is for arc to have widespread adoption then being able to leverage racket in a meaningful way will help get you there.

Currently the ability to drop into racket is not getting people to use arc, it still seems people would rather just use racket. http://arclanguage.org/item?id=20781

IMO, It would be better if arc had implicit methods that provide access to racket capabilities. In Clojure having libraries, name spaces, and a seamless interfaces to java translated into a plethora of libraries for Clojurians to utilize. Can we not do the same? Well if the goal is for "widespread adoption" then we need to.
