Clojure struggles with staged programming because of JVM limitations. "The deeper issue here is that JVM bytecode is fundamentally static: it's not allowed to contain references to objects that only exist at runtime. In languages that have a built-in concept of a "runtime image," like Smalltalk or some Lisps, the line between static code and runtime data is blurred."
