Comment(by duncan):

 Yeah, something like that. I was thinking of a slightly more general
 interface that would allow other/different implementation options on
 different machines or in different contexts (e.g. debug builds).

 Something like, Resources_$packagename.hs:
 openResource :: String -> IO Handle
 So it's very much like the current Paths_$packagename.hs:
 getDataFileName :: FilePath -> IO FilePath
 but it combines locating with opening the resource as an ordinary
 `Handle`. Doing IO to perform the open and providing a `Handle` gives us
 quite a lot of implementation options. We can still do the ELF `foreign
 import ccall "&"` stuff or we can use ordinary files (e.g. for debug and I
 think MacOSX bundles use separate files too), and for Win32 we can use the
 Windows resource APIs. This relies on the new base-4 `Handle` stuff which
 lets you create custom handle implementations.
