Field accessors unnecessarily kept alive
Suppose you have a record with some non-exported field accessors, like so:
module Lib (Rec) where
data Rec = Rec
{ f1 :: Int
, f2 :: Int
, f3 :: Int
, f4 :: Int
, f5 :: Int
}
Code for fields f1
, f2
... are redundantly generated, optimized etc. and they made it to the object file, causing wasted compile times and bloated object files.
