I'm curious because I'd like to turn my external STG interterpreter to an abstract interpreter using the AAM (Abstracting Abstract Machines) method.<o:p></o:p></p>

This approach seems promising to me because a single Haskell code base (ext STG interpreter) could be the specification of the Haskell operational semantics and also be a detailed static analyzer that could help optimization transformations.<o:p></o:p></p>

I'm interested in any attempt that happened during GHC/Haskell evolution.<o:p></o:p></p>
