Hey Kevin, thanks for getting back to me.
The splice is 'etal' (which is null). I should have excluded it for
clarity. What you're actually seeing is the map being unquoted:
user=> `(commands/add *~processed* ~@etal)
(commands/add {:tag :user, :username "stub" ... }) ;; 'etal' does not show
up in what gets evaluated - ** first in this list is a function
Now, if I try to eval that, I get the said error.
user=> (eval `(commands/add *~processed*))
java.lang.IllegalArgumentException: Wrong number of args (3) passed to:
PersistentArrayMap (NO_SOURCE_FILE:324)
And I had tried macroexpand (here and in the containing function), and got
the same error:
user=> (macroexpand (eval `(commands/add *~processed*)))
java.lang.IllegalArgumentException: Wrong number of args (3) passed to:
PersistentArrayMap (NO_SOURCE_FILE:324)
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. Thanks again for the feedback. It's something small that
I'm missing.
