Hi, the behavior you describe is not specific to macros, but is due to the use of aliases
after: (require '[foo.bar :as b]) this will give you false: (= 'foo.bar/x (first '(b/x))) while this will give you true: (= 'foo.bar/x (first '(foo.bar/x))) one way to solve it, is comparing the resolved vars instead of the names: (= (resolve 'foo.bar/x) (resolve (first '(b/x)))) ;=>true (= (resolve 'foo.bar/x) (resolve (first '(foo.bar/x)))) ;=>true hth, Gianluca On Saturday, October 3, 2015 at 3:03:49 PM UTC+2, Andrey Antukh wrote: > > Hi! > > I have a little trouble writing a macro because I'm getting unexpected > (for me) behavior. > > Let see some code: > > (ns foo.bar) > > (defn debug > [x] > (println "debug:" x) > x) > > (defn debug-expr? > [expr] > (and (seq? expr) > (symbol?
