That part about speed was more about my general frustration with the "immutable is fast" and "mutable is slow" meme that I hear too frequently. While that can be the case, it isn't always 100% true. Your language and how you use it can play a huge part.
I'm hoping to learn more about clojure data structures in the coming months, so much good stuff.
My guess would be that immutable clojure is still faster than say mutable ruby though.
I don't think anybody is arguing that trie lookup is faster than array lookup.
But when it comes to passing data between parts of the system, zero cost copies are much faster than copying buffers or objects.
