deftype code reload oddity

Here's something a little perplexing that I discovered by trial and error: if you reload (using require :reload) a clj file containing a deftype implementing clojure interfaces (e.g. ISeq, etc.) plus some functions, the functions will be reloaded but not the deftype implementation code. That is,

Re: Why (memoize (fn [_#] (gensym "node")) in rhizome?

Seems like a good use of “delay”, yeah? Slightly different calling semantics, of course, but still: user> (def f (delay (gensym "node"))) #'user/f user> @f node3330 user> @f node3330 Sam Ritchie (@sritchie) RaceHub Co-Founder 703.863.8561 www.racehubhq.com Twitter

Re: Why (memoize (fn [_#] (gensym "node")) in rhizome?

(memoize (fn [_#] (gensym "node")) How is that different than (gensym "node") The latter returns a string, e.g., "node18051", the former returns a function that, when called, returns a string. Wrapping it in memoize just ensures that if you call it multiple times with the same argument, you g

Why (memoize (fn [_#] (gensym "node")) in rhizome?

I'm always interested in the stuff Zach Tellman does, though I don't always understand it. I'm curious about this bit: (memoize (fn [_#] (gensym "node")) How is that different than (gensym "node") I only see with-gensyms called once, so I assume the goal is to have dynamic bindings set up f

Reading Clojure expressions

Hello, I'm not sure the proper terminology -- reading might be wrong. The idea is I'd like to mimic behavior in most Clojure development environments where given a buffer and a position you can find related expressions. e.g. previous expression, enclosing expression, etc. Preferably the resu
