sort.hs has 50 top level functions. One of them is main, and the others are all reachable from it. ghc -O sort.hs ghc --show-iface sort.hi The only functions listed are variants of main. Dropping -O leaves one variant of main only; the other 49 functions have disappeared. It is, by the way, something of a nuisance that if you do ghc sort.hs ... ghc -O sort.hs it insists "compilation NOT required" despite the fact that the previous compilation was with materially *different* options. (GHC 6.12.3) Given this clue I was able to get the information I wanted by exporting all the functions. This is the wrong interface. If a programmer is concerned that strictness analysis might not be finding something they thought was strict, they would ideally like to have *all* the functions reported, but at a minimum, all of the top level functions.
