[Haskell-cafe] Help me TH code.

Tue, 26 Oct 2010 20:05:31 -0700 

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')

So how to use TH write 'parse' function? 

Thanks!
