You don't need TH here, I think.
You can write a class Ask:
class Ask a where
Unless you have a 'real' type for parse sometime during compile time, TH
won't be able to generate it. A good rule of thumbs is that if you can't
write the code yourself, then you can't get TH to do it either.

Hi all,
I want use TH write some function like below:
data DataType = StringT
| IntT
| CharT
parse :: [(String,DataType)] -> (TypeA, TypeB, ... TypeN)
Example:
parse [("string", StringT), ("001", IntT), ("c", CharT)]
will return:
("string", 001, 'c')
