I am looking more for the way to serialize intermediate parser computations. The first problem is, actually, easy one. ;)
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.
Thank you very much. I think, I will try Template Haskell approach, I prefer combinators over the generators.
