I've asked this before and nobody answered, so I take it that nobody knows the answer... Does GHC *ever* do an in-place update on anything?
no. this will break GC's heart :) and it really breaks it as far as you start to work with updateable arrays. look for details at http://haskell.org/haskellwiki/Modern_array_libraries
Does the STG even have a command for that?
hm. there are ghc primitives that work with mutable arrays. look for primops.txt.pp in ghc sources. btw, you doesn't need to use unix in order to play with ghc HEAD - you can download compiled windows binary -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
