I suspect the reason for this is that GHCi never needed this functionality. What do you intend on doing with it? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15739#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I don't have any plans for it but it could be confusing if someone just looks at the API. pokeItbl also seems to implement it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15739#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
