If we have this module:

module Q where

v :: a
v = let x = x in undefined

w :: a
w = let y = 'a' in undefined

then we get warned that y is unused, but not that x is:

q.hs:8:8: Warning: Defined but not used: `y'

Forgot to say:

Compiling with ghc -fforce-recomp -Wall -c q.hs.

Also affects the HEAD.

Resolution: fixed
Status: newclosed

This doesn't merge cleanly, and I (the reporter) don't think it's very important for 6.8.3, so I'm closing it as it's fixed in the HEAD.
