You would have to fix *all* warnings.
If there is not a principled reason swank works the way it does, let's
fix it. I'll get to it eventually myself if nobody else does, but it
isn't near the top of my list.

So if someone produces a fork of incanter that doesn't have the
warning (or David fixes up Incanter), then the problem goes away?
Because the other place I see the warnings coming out of is swank
itself.

I would love to see somebody fix this, and I think it is simpler (and
probably conceptually correct) to make swank use a PrintWriter,
instead of
requiring all possible tools to do a check for swank's sake. See [2]
Until this is fixed, swank is busted for any app that produces a
last-var-wins warning.

Update: Using the latest labrepl commit (fa89411ae "use private
compojure snapshot"), I'm now able to pull in incanter and use it
(albeit with tons of warnings about group-by and flatten from both
incanter and swank)...but only if I use script/repl via inferior-
lisp.
I still can't get swank to work. It fails with the same error as
before [1].
But at least I'm unblocked.
