And it's usage is far less generalised than macros in LISP.
It is not an usual solution to write acamlp4 preprocessor.

Any macro is an example of that.
For example, from clojure/core.clj
(defmacro ->

I assume you can see why parameters are data structures (or just plain
data, if you want speed). Operations - or function calls - are data
structures because it makes sense. Especially in Li
