Comment (by bgamari):

 For what it's worth, I have a rather under-advertised GHC core-to-core
 [[http://github.com/bgamari/ghc-dump|plugin]] which dumps Core to a file
 in machine-readable form for later inspection. There are also tools for,
 among other things, pretty-printing the files in the human-readable(?)
 form we all love in addition to a library allowing you to inspect the
 representation in GHCi. This is nice for a variety of reasons,

  * You have more control over what bits to show
  * You can start with a minimal dump of the program and then decide to
 show more details later without recompiling your program
  * You can easily search for bindings by name, type, etc.
  * Other nice reasons that this margin is too small to contain

 One feature it currently misses that I would love is the ability to diff
 files up to alpha-equivalence. However, I feel like this advertisement has
 gone on for too long already.
