Try
(defmacro my-macro [a-map & forms] ; Naive
You can use eval to retrieve the value of a-map when the macro is
expanded.
(let [value (eval a-map)]
`(binding ~(vec (process-a-map value)) ~...@forms))
I've programmed some substantial programs now in Clojure though, and

; Turns maps into corresponding vectors.
; (process-a-map my-map) returns ['*foo* :blah].
