Dear all,
Given a node type from singly linked list:
class Node {
int val;
Node next;
}
How do I extend it so `(seq node)` will return a sequence of values? And
generally first, rest, and next will work on node too.
While in Java, we could define the class to implement Iterable to achieve this.
In Clojure we do have `extend-type`, but it seems not accepting interfaces to
extend, nor do I find protocol for seqable.
So generally, given a class defined in Java, assuming it is not available for
rewrite, how shall we extend the class to participate in sequence operations in
Clojure?
Thanks in advance!
