I'm trying to make a macro my-macro so that the last statement in:
(def my-map {:a 2})
(defn process-a-map [arg] ...)
; Turns maps into corresponding vectors.
; (process-a-map my-map) returns ['*foo* :blah].
(my-macro a-map ; Last statement
(do-something))
expands to:
(binding [*foo* :blah] (do-something))
; process-a-map was called on a-map
But I'm getting stuck because a-map always gets passed into my-macro
as a symbol.
(defmacro my-macro [a-map & forms] ; Naive implementation
`(binding ~(vec (process-a-map a-map)) ~...@forms))
Here, when my-macro is called, process-a-map receives the symbol 'a-
map, rather than what I want—a-map's value, {:a 2}. What can I do? Is
this impossible for macros to deal with?
