Perhaps your preprocessor could just place a suitable 'import' in the
generated Haskell module?

Along the same lines: put something like this in the generated module
requirePage :: ()
requirePage = f page
f :: PageType -> ()
f _ = ()
IIRC if you use a name beginning with underscore, GHC won't warn that it
.signature: Too many levels of symbolic links
