status of template haskell + cross compiling plans for 7.8?

Hey All, Whats the story planned for template haskell + cross compiler support come ghc 7.8? I understand theres a lot of Template Haskell design underway, some of which will help support tools like Manuel's Inline-Objective-C work. Does this mean that factored out within this reorganization is a better story for cross compilation? Especially since one kill "app" for the Inline-Objective-C template haskell work would be writing IOS applications. Though I guess that also touches on the need to sort out supporting "FAT" ARM binaries too, right? This intersects with a few different large subsets of tickets, so i'm not sure if any single ticket is the right fora for this question. thanks! -Carter
