[Haskell-cafe] Any generic serializer to String? was: Any working example of using genericserialize?

[Dimitry Golubovsky]

OK, I got it to work with gread/gshow.

However I have noticed this:

*Main> (gread $ gshow $ FuncExpr 0 [] (EmptyStmt 0)) :: [(Expression
Int, String)]
[(FuncExpr 0 [] (EmptyStmt 0),"")]

vs.

*Main> (gread $ gshow $ FuncExpr () [] (EmptyStmt ())) :: [(Expression
(), String)]
[]

Or even narrower:

*Main> (gread $ gshow 1)::[(Int, String)]
[(1,"")]

vs.

*Main> (gread $ gshow ())::[((), String)]
[]

that is, the unit type does not work well with gread/gshow, likely
because inner parentheses are not parsed as a constructor.

*Main> gshow ()
"(())"

Is this a known bug?

Thanks.
