This would * save some memory (two words per array), * make updates cheaper (no writing to the card table), and * make GC faster (no traversing the card table). The use case is the unordered-containers package, which uses small arrays to implement a hash array mapped trie. A starting point would be [changeset:0417404f5d1230c9d291ea9f73e2831121c8ec99/ghc], which added the card table to the current array type. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8923> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
