http://www.lambdassociates.org/blog/klambda.htm suggests a possible bootstrapping mechanism, some kind of reduced set of clojure functionality "ur-clojure" that is designed to be easy to write and interpreter for, and a compiler backend that generates ur-clojure, after compiling the compiler+platfo

Re: Bug in 1.3 with sets as functions?

Sets when used as functions are not predicates the do not return true or false based on membership. They return the looked up value, in this case false. You can say "well I passed in the value, why would I want it back" but sets don't need to return an identical object, just an equal object (could

Re: How would I learn more about Clojure's class loading system?

There are a number of different possibilities. Without anything more specific the only realistic answer is "read the source of all the libraries you are using, and of clojure, and of lein and look for tricks with classloaders" Clojure does some classloader fiddling, but so do most jvm build tools
