Comment (by Austin Seipp <austin@…>):

 In [changeset:"07ace5c221adbb1675413a0fac300a9f7913c234/ghc"]:

 add -th-file which generates a th.hs file

 Summary:
 see Trac #8624

 similar functionality is now available
 with -ddump-to-file -ddump-splices

 However, users are already accustomed to -ddump-splices
 having a particular format, and this format is not completely valid code
 The goal of -th-file is to dump valid Haskell code

 Additionally, the convention of -ddump-to-file is to name the file after
 the flag, so the file is .dump-splices
 Given that the goal of the new flag is to generate valid Haskell,
 The extension should be .hs

 Additionally, -ddump-to-file effects all other dump flags

 Test Plan:
 look at the output of using the -th-file flag
 and compare it to the output of using -ddump-to-file and -ddump-splices
 I want to add test cases, but just need some pointers on getting started
 there
