It seems to me that instead of working around this, we should add a pragma to suppress the warning at the pattern site. Maybe something like let {-# PARTIAL_MATCH #-} Just a = blah blah That way GHC can see that you noticed the partial match and that you're okay with it.

Hello,
The recent GHC added incomplete-uni-patterns to the -Wall option. So, we have a waning with the following code:
let [addr,port] = args
To avoid this, I changed the code to:
let addr = head args port = head $ tail args
In my opinion, this seems Lisp rather than Haskell.
Also, I need to avoid:
let Just val = mval
Rahter, I use:
let val = fromJust mval
This is annoying to me.
How do you get along with incomplete-uni-patterns? I would like to know the best current practice.
