Inheritance example with Abstract classes

[zcaudate]

One problem that I've always faced with clojure is that it's not possible to derive things from Abstract classes.

Can you create an example showing how to do it with JiSE?

I will prepare some documentation on the JiSE syntax in the future, but shortly: You can use the optional "inheritance vector" syntax to specify the parent class and/or implemented interfaces.
For example, if you want to define a class that is derived from the class P and implements the interfaces I1 and I2, you can write something like the following:

(require '[jise.core :refer [defclass]])

(defclass C [P I1 I2] ...)

This is an example that I ran into trouble porting

Another thing that is difficult is with annotations. I think orbit uses them well but it's not that well supported with clojure.

Another interesting use case might be this:

This would be another project that'd be great to get working:
