Hi Timothy, One paragraph summary:
When a macro expands to case inside of a go-block, it appears that the _ELSE_ clause of the case is always run. (Even after a previous clause has matched.) Slightly longer summary: In these lines: https://github.com/txrev319/bug-report/blob/master/src/app.cljx#L11-L20 The macro is supposed to expand into: (case (:tag {:tag :dog}) :dog "woof woof" "unrecognized") When we do not use go, we get the result as expected. When we put it into a go-block, it appears that both the :dog "woof woof" branch and the "unrecognized" branch are _BOTH_ being executed -- when only one should be executed.
