I don't believe in this data structure. Its ill informed Rich Hickey nonsense and it doesnt scale and has no purpose but to seem clever.
How so?
> it doesnt scale
I take it that if many of Clojure's primitives are built using this data structure, it doesn't scale either? Yet some else mentioned how performant it actually is, given that it doesn't copy everything, but merely shares commonality.
Given your past comments, this isn't the first time you say something without knowing much about it.
