Comment (by simonpj):

 > Given a nested splice, how do you associate it with a post-processor

 Well, GHC would apply the post-procssor to the expression for the top-
 level splice.  It would pass the expression, so no need for any other
 association.

 I don't understand the nested-splice issue.

 Yes, it's a bit like a plugin.  But then TH splices are already a bit like
 a plugin: both provide code that the compiler links dynamically and runs
 at compile time.

 I'm a bit ouf of my depth.  Is anyone else interested in this?  Designing
 for a single use-case is sometimes justified, but it's better if there are
 more.
