Comment (by GregWeber):

 A big problem here is that `-ddump-to-file` is a global flag. I assume
 dumping to stdout is the default because users want that ephemeral
 behavior. The design for this ticket is that a user always wants to save
 it to a file, and that should not have to make all other dumps go to a
 file. If someone wants to ephemerally dump splices to stdout `-ddump-
 splices` is already there, well known, and better suited to the job.
 Additionally, I want a `.hs` file to signify that the output is valid
 Haskell, not just a dump in an ad-hoc format, whereas with dumping the
 convention is `dump-FLAG`.

 So I did intentionally want to get away from dumping but I am definitely
 open to ideas for better naming.
