Oh sorry, were the colors off? Let's try this.
The map was actually unquoted. 'etal' (which was null) was unquote-spliced. I excluded it for clarity: * user=> `(commands/add ~processed) * * result=> (<my-function> <my-map>) ;; ** first in this list is a function * Now, if I try to eval that, I get the said error. * user=> (eval `(commands/add ~processed))* * result=> java.lang.IllegalArgumentException: ...* And I had tried macroexpand (here and in the containing function), and got the same error: * user=> (macroexpand (eval `(commands/add ~processed)))* * result=> java.lang.IllegalArgumentException: ...* You're right that the repl is using the map as a function. But I don't understand why when 'commands/add' function was the first thing in the return list. And macroexpand is yielding the same error . This is what had me so perplexed. Hopefully this reads a bit better.
