Probably you'll have to create a data constructor for each step
of your parser.

AFAIK, one of HAppS modules does a similar transformation via
Template Haskell.  The functions specify transactions, and each
transaction is converted to a serializable data type.  Then it's
possible to create a transaction log by serializing them before
their execution.

Of course you could also modify Happy instead of writing a TH
transformation.  Both are preprocessor.  TH would be more
convenient, though.
