dependingOn in 6.6

I was wondering if we could be sure to get dependingOn :: a -> b -> a dependingOn = .... in ghc 6.6? this has been discussed before, it is implemented in jhc and I have found all sorts of use for it as it can be used to control let floating and inlining in a nice general way and is trivial to implement. (one for ghc was posted before based on primitives it already implements) we just need to decide on a module to export it. the meaning is that x = ... `dependingOn` y returns x with an artificial dependency on y. so things using x cannot be floated out above where y is defined.
