@genekim Ate some dog food, and found the same problem, and yet another bug. 😢 Use:

(ns my.namespace 
  (:require [testify :refer [eval-in-ns]))
(defmacro mytest [& _])
(mytest 
  (println "Hello"))
(eval-in-ns 'my.namespace #'mytest)  

I'll have a look at it...

Thank you @genekim

My apologies for slow response — tied up for next 3 days. But will happily try out new versions and so forth afterwards!!! TY and keep up the great work!!
