See here and the linked paper: http://www.haskell.org/haskellwiki/Ministg I don't know of any way to examine this for a running program. You can get GHC to spit out core and STG using -ddump-core and -ddump-stg flags: http://www.haskell.org/ghc/docs/6.12.2/html/users_guide/options-debugging.html#id595218 I hope that helps, Jason
