Based on section 5.2 of this paper:
I wonder if the Data instance I provided is the best possible option
with out modifying SYB. And that the optimal solution would be to
extend ConstrRep to support Text as a primitive:
= AlgConstr ConIndex
| IntConstr Integer
| FloatConstr Double
| StringConstr String
| TextConstr Text -- does not really exist
-- Defined in Data.Data
With the unfortunate side-effect of making syb depend on text.
