If I understood TH correctly, the expressions after the "splice operator" $ 
describe vanilla source Haskell.  And I assumed that it's this vanilla source 
code which -ddump-splices outputs. (I've never checked this myself.)  So why 
isn't it possible to replace the splice parts in the *original* Haskell 
source file with the outputs of -ddump-splices?  This could be done via some 
search and replace at the text level though this is, of course, not very 
elegant.
