I just wrote a useful combinator for quasi-quoters, you may want to
include it in the Quote module. It takes an existing quasi-quoter and
produces a quasi-quoter that statically reads and parses the content of a
file.
{{{
quotefile :: QuasiQuoter -> QuasiQuoter
quotefile (QuasiQuoter exp pat) = QuasiQuoter (ff exp) (ff pat) where
ff old s = runIO (readFile s) >>= old
}}}
This is useful when you need to quote data from a separately maintained or
generated source file.
