Another example, similar to Manuel's work but for GHCJS JavaScriptFFI
is ghcjs-ffiqq: https://github.com/ghcjs/ghcjs-ffiqq . There is some
automatic marshalling of arguments and results using the ToJSRef /
FromJSRef typeclasses. I'm working on integrating the improvements in
these typeclasses back into ghcjs-base. The quasiquoter might be moved
there too, but I'm not sure yet.
The (ugly) implementation is here:
https://github.com/ghcjs/ghcjs-ffiqq/blob/master/src/GHCJS/Foreign/QQ.hs
Adapting to ccall imports should be straightforward, but implementing
the full functionality would require a bit more stub code generation,
since this code depends on GHCJS' native support for inline foreign
import argument placeholders ($1, $2, $3 etc) placeholders.

This may be relevant. http://www.cse.unsw.edu.au/~chak/papers/CMCK14.html Manuel gave a talk about something like this at the Haskell Symposium.
