Despite the interesting discussing which has followed this question I think
that in orde to approach this specific problem the use of a specific
compiler-writers toolset such as the uuagc
(http://hackage.haskell.org/package/uuagc-0.9.29)) system is to be preferred;
it provides aneffiicent and

As an example, consider the simplified ast types:
data Exp
=
Hello.
In his book Modern Compilder Implementation in ML, Appel presents a
compiler project for the Tiger programming language where type checking
and intermediate code generation are intrinsically coupled.
There is a function
transExp :: Absyn.Exp - (Tree.Exp,Types.Type)
that do semantic
Martijn van Steenbergen has a good blog post that describes the method I
generally use:

In his example he annotates the expression tree with position information,
but you can use the same
I would be inclined to add type annotations as an extra constructor of
the expression representation type.
data Exp
= IntExp Integer
| VarExp Symbol
| AssignExp Symbol Exp
| IfExp Exp Exp (Maybe Exp)
| CallExp Symbol [Exp]
| LetExp [Dec] Exp
| Exp `HasType` Ty

Ah, I found the attachment on your other email.
I would recommend using the Fix and Ann types, instead of the AnnFix type.
I modified your code a bit (and fixed the Show instances etc...) and put it
