I now have a vague clue how to do what I wanted. I wanted to substitute
types in place... a silly example would be to convert Ints to Floats and
Floats to Ints...
(3 :: Int, 4.0 :: Float) -> (3.0 :: Float, 4 :: Int)
I already have a function that will convert the input to:
[("3",IntType),("4.0",FloatType)]
So I can then manipulate the list in this form to:
[("3.0",FloatType),("4",IntType)]
All I now need to do is reconstruct back into the data structure...
I have however been unable to find any docs on "gunfold" which I
think is the way to do this...
If somebody point me to some documentation for gunfold, or
help in any way I would be very grateful...
Regards,
Keean Schupke.
