-* Test effect of eta-expanding past (case x of ..)
-
-* Bottom strictness isn't right.  Should be (eg) SSX, not just X.
-
-* Enumeration types in worker/wrapper for strictness analysis
-
-* Use (!) types in data cons to unbox.
-
-* Check constant folding
-
-* .hi file isn't updated if the only change is to the exports.
-  For example, UgenAll.lhs re-exports all of U_binding.hs; when a data type
-  decl in the latter changes, the .hi file for the former isn't updated.
-  I think this happens when a module exports another mdodule thus:
-
-	module UgenAll( module U_binding, ... ) where
-
-* This should be reported as an error:
-	data T k = MkT (k Int#)
-
-* Bogus report of overlapped pattern for
-	f (R {field = [c]}) = 1
-  	f (R {})	      = 2
-  This shows up for TyCon.maybeTyConSingleCon
-
-*  > module Main( main ) where
-
-   > f :: String -> Int
-   > f "=<" = 0
-   > f "="  = 0
-   
-   > g :: [Char] -> Int
-   > g ['=','<'] = 0
-   > g ['=']     = 0
-   
-   > main = return ()
-   
-   For ``f'' the following is reported.
-   
-   tmp.lhs:4: 
-    Pattern match(es) are overlapped in the definition of function `f'
-            "=" = ...
-
-   There are no complaints for definition for ``g''.
-
-* Without -O I don't think we need change the module version
-  if the usages change; I forget why it changes even with -O
-
-* Record selectors for existential type; no good!  What to do?
-  Record update doesn't make sense either.
-
-  Need to be careful when figuring out strictness, and when generating
-  worker-wrapper split.
-
-  Also when deriving.
-
-* Consructor re-use via CSE

-		Notes on module dependencies

-
-The Name/Var/Type group is a bit complicated. Here's the deal
-Things in brackets are what the module *uses*.
-A 'loop' indicates a use from a module compiled later
