Wow, I didn't seriously expect it was a real bug. This is my first
time finding a confirmed compiler bug. Thanks for the response!

I don't know enough to make a case for or against this, but the

I'm not sure I understand.
f :: Int -> Int -> Int -> Int
f = \x y z -> x + y + z

Hi,
I was adding a strict pre-order fold to the Data.Map module and I ran into
this slightly surprising behavior. Modeled on foldl' for lists I defined

foldlWithKey' f z0 m = go z0 m
where
go z Tip = z
