Is it really impossible to just use the plaintext as code in Template Haskell? It would really be nice if you could use any bit of Haskell wherever you can use a variable (but it's just nice-to-have, not worth playing with GHC's code just to get it).

It was until someone else wrote a library for us =) [1]. We just need to unpack the QuasiQuoter data type and use it inside Hamlet's quasiquoter.

Michael, were you aware of this library?

Cheers,

It should be noted that the hse-qq library doesn't handle infix operator precedence properly. There are proposals to remedy this; but it requires changes to GHC, see http://hackage.haskell.org/trac/ghc/ticket/4430 http://hackage.haskell.org/trac/ghc/blog/Template%20Haskell%20Proposal Cheers,
