Hello, I've been investigating the basic data structures and their underlying concepts in Clojure, particularly focusing on the definitions of coll, seq, map, vector, set, etc. and their inclusion relationships.
I saw a Venn diagram in this page[1]. Although it is as of Clojure 1.3, I confirmed it is still correct. "Counted" interface has its only method count() and it implies that we can get the explicit size of a "Counted" collection. However, IPersistentCollection, which is actually the definition of collections, also has count() method. It's a bit surprising to me that even LazySeq supports count() (indirectly via ISeq). Questions: If IPersistentCollection has count() method, What is "Counted" for? Is it always reasonable for LazySeq to support count() method? Shouldn't there be an explicit "CountedLazySeq", Thanks.
