However, the tick remains in the unfolding
* Why? If it is dropped in the RHS why isn't it dropped in the unfolding too? At the risk of stating the obvious, because the tick is around a `Case`, not a `Var`.
* Also, when that unfolding is later inlined at a call site, why isn't
the tick eliminated then? My test case illustrates an example of this, hopefully it is clear from the comments what is going on. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5889#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
