I checked out in the Haskell list whether somebody would like to write
parser generator files for Bison generating Haskell as output:

Then Simon Marlow said that the Haskell parser generator Happy has some
typing features and a monad wrap.

To me, it sounds as though one needs (for the former) a feature %typed not
tied to %union which merely sets the typed internal variable, plus (for the
latter) something like a
  %definition <name> <definition>
generating M4 macros, as I suggested.

In addition, for C++, I need the pre- and post-prologue to not be tied to
