Reader: Source code (text) -> Clojure reader -> Data structures (code)
Compiler: [function or special form] -> bytecode, [macro] -> Data
structures (code)
Runtime: Data structures are evaluated:
Literals -> to themselves (1->1, "some string" -> "some
string", :some-key -> :some-key)
Symbols -> to a value (from a var in some namespace)
Lists -> call to a function or special form.
A call to a macro take place at compile time before the data structures
(code) are evaluated. It is a transformation tool of data structures (code)
to data stuctures (code) before the evaluation take place.
You are using the wrong tool for the job,
if you want to iterate over the contents of a variable (runtime), use a
function.
