The QuasiQuoter type, a value q of this type can be used
in the syntax [q| ... string to parse ...|]. In fact, for
convenience, a QuasiQuoter actually defines multiple quasiquoters
to be used in different splice contexts; if you are only interested
in defining a quasiquoter to be used for expressions, you would
define a QuasiQuoter with only quoteExp, and leave the other
fields stubbed out with errors.
This is exposed both from the template-haskell-quasiquoter and template-haskell packages.
Consider importing it from the more stable template-haskell-quasiquoter if you don't need the full breadth of the template-haskell interface.
